PRODUCT DESCRIPTION

The AD816 consists of two high current drive and two low
noise amplifiers. These can be configured differentially for driv­ing low impedance loads and receiving signals over twisted pair
cable or could be used independently for single ended driving
application such as correction circuits within high resolution
CRT Monitors.

FUNCTIONAL BLOCK DIAGRAM

The two high output drive amplifiers are capable of supplying
a minimum of 500 mA continuous output current and up to
1A peak output current, and when configured differentially,

40 V p-p differential output swing can be achieved on ±15 V
supplies into a load of 50 Ω. The drivers have 120 MHz of
bandwidth and 1,500 V/µs of differential slew rate while

featuring total harmonic distortion of –68 dB at 1 MHz into a

100 Ω load, specifications required for high frequency telecom-

munication subscriber line drivers.

The low noise voltage feedback amplifiers are fully independent
and can be configured differentially for use as receiver amplifi­ers within a subscriber line hybrid interface or individually for

signal conditioning or filtering. The low noise of 4 nV/√Hz and

distortion of –68 dB at 1 MHz enable low level signals to be
resolved and amplified in the presence of large common-mode

voltages. 100 MHz of bandwidth and 180 V/µs of slew rate

combined with a load drive capability of 70 mA enable these
amplifiers to drive passive filters and low inductance coils. The
AD816 has thermal overload protection for system reliability
and is available in low thermal resistance power packages. The

AD816 operates over the industrial temperature range (–40°C
to +85°C).

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the
AD816 is limited by the associated rise in junction temperature.
The maximum safe junction temperature for the plastic encap­sulated parts is determined by the glass transition temperature

of the plastic, about 150°C. Exceeding this limit temporarily

may cause a shift in parametric performance due to a change in
the stresses exerted on the die by the package. Exceeding a

junction temperature of 175°C for an extended period can result

in device failure.

The AD816 has thermal shutdown protection, which guarantees
that the maximum junction temperature of the die remains below a
safe level. However, shorting the output to ground or either power
supply for an indeterminate period will result in device failure.
To ensure proper operation, it is important to observe the derat­ing curves and refer to the section on power considerations.

It must also be noted that in high (noninverting) gain configura­tions (with low values of gain resistor), a high level of input
overdrive can result in a large input error current, which may
result in a significant power dissipation in the input stage. This
power must be included when computing the junction tempera­ture rise due to total internal power.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.

WARNING!

Although the AD816 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

AD816

THEORY OF OPERATION (DRIVER)

The AD816 driver is a dual current feedback amplifier with high
(500 mA) output current capability. Being a current feedback
amplifier, the AD816 driver’s open-loop behavior is expressed

/∆I

as transimpedance, ∆V

, or TZ. The open-loop trans-

O

–IN

impedance behaves just as the open-loop voltage gain of a volt­age feedback amplifier, that is, it has a large dc value and de­creases at roughly 6 dB/octave in frequency.

Since R
just T

is proportional to 1/gM, the equivalent voltage gain is

IN

× g

, where the gM in question is the transconductance

Z

M

of the input stage. Figure 42 shows the driver connected as a
follower with gain. Basic analysis yields the following results:

Recognizing that G × R

IN

the first order that bandwidth for this amplifier is independent
of gain (G).

Considering that additional poles contribute excess phase at
high frequencies, there is a minimum feedback resistance below
which peaking or oscillation may result. This fact is used to
determine the optimum feedback resistance, R

. In practice

F

parasitic capacitance at the inverting input terminal will also add
phase in the feedback loop so that picking an optimum value for

can be difficult.

R

F

Achieving and maintaining gain flatness of better than 0.1 dB at
frequencies above 10 MHz requires careful consideration of
several issues.

Choice of Feedback and Gain Resistors

The fine scale gain flatness will, to some extent, vary with
feedback resistance. It is therefore recommended that once
optimum resistor values have been determined, 1% tolerance
values should be used if it is desired to maintain flatness over a
wide range of production lots. Table I shows optimum values
for several useful gain configurations. These should be used as a
starting point in any application.

DRIVER DC ERRORS AND NOISE

There are three major noise and offset terms to consider in a
current feedback amplifier. For offset errors refer to the equa­tion below. For noise error the terms are root-sum-squared to
give a net output error. In the circuit below (Figure 43), they
are input offset (V

THEORY OF OPERATION (RECEIVER)

Each AD816 receiver is a wide band high performance opera­tional amplifier. It also provides a constant slew rate, bandwidth
and settling time over its entire specified temperature range.

The AD816 receiver consists of a degenerated NPN differential
pair driving matched PNPs in a folded-cascode gain stage. The
output buffer stage employs emitter followers in a class AB
amplifier which deliver the necessary current to the load while
maintaining low levels of distortion.

A protection resistor in series with the noninverting input is
required in circuits where the input to the receiver could be
subject to transients on continuous overload voltages exceeding

the ±6 V maximum differential limit. The resistor provides

protection for the input transistors, by limiting their maximum
base current.

PRINTED CIRCUIT BOARD LAYOUT
CONSIDERATIONS

As to be expected for a wideband amplifier, PC board parasitics
can affect the overall closed-loop performance. Of concern are
stray capacitances at the output and the inverting input nodes. If
a ground plane is to be used on the same side of the board as
the signal traces, a space (5 mm min) should be left around the
signal lines to minimize coupling.

POWER SUPPLY BYPASSING

Adequate power supply bypassing can be critical when optimiz­ing the performance of a high frequency circuit. Inductance in
the power supply leads can form resonant circuits that produce
peaking in the amplifier’s response. In addition, if large current
transients must be delivered to the load, then bypass capacitors

(typically greater than 1 µF) will be required to provide the best

settling time and lowest distortion. A parallel combination of

10.0 µF and 0.1 µF is recommended. Under some low frequency
applications, a bypass capacitance of greater than 10 µF may be

necessary. Due to the large load currents delivered by the AD816,
special consideration must be given to careful bypassing. The
ground returns on both supply bypass capacitors as well as signal
common must be “star” connected as shown in Figure 44.

POWER CONSIDERATIONS

The 500 mA drive capability of the AD816 driver enables it to

drive a 50 Ω load at 40 V p-p when it is configured as a dif-

ferential driver. This implies a power dissipation, P

, of nearly

IN

5 watts. To ensure reliability, the junction temperature of the

AD816 should be maintained at less than 175°C. For this rea-

son, the AD816 will require some form of heat sinking in most
applications. The thermal diagram of Figure 45 gives the basic

relationship between junction temperature (T

Normally, the AD816 will be soldered directly to a copper pad.

Figure 47 plots θ

against size of copper pad. This data pertains

JA

to copper pads on both sides of G10 epoxy glass board connected
together with a grid of feedthroughs on 5 mm centers.

This data shows that loads of 100 ohms or greater will usually
not require any more than this. This is a feature of the AD816’s
15-lead power SIP package.

An important component of θ

is the thermal resistance of the

package to heatsink. The data given is for a direct soldered
connection of package to copper pad. The use of heatsink
grease either with or without an insulating washer will increase
this number. Several options now exist for dry thermal connec­tions. These are available from Bergquist as part # SP600-90.

The AD816 is equipped with a thermal shutdown circuit. This
circuit ensures that the temperature of the AD816 die remains
below a safe level. In normal operation, the circuit shuts down

the AD816 at approximately 180°C and allows the circuit to
turn back on at approximately 140°C. This built-in hysteresis

means that a sustained thermal overload will cycle between
power-on and power-off conditions. The thermal cycling typi­cally occurs at a rate of 1 ms to several seconds, depending on
the power dissipation and the thermal time constants of the
package and heat sinking. Figures 48 and 49 illustrate the ther­mal shutdown operation after driving OUT1 to the + rail, and
OUT2 to the – rail, and then short-circuiting to ground each
output of the AD816. The AD816 will not be damaged by
momentary operation in this state, but the overload condition
should be removed.

Other Power Considerations

There are additional power considerations applicable to the
AD816. First, as with many current feedback amplifiers, there is an
increase in supply current when delivering a large peak-to-peak
voltage to a resistive load at high frequencies. This behavior is
affected by the load present at the amplifier’s output. Figure 12
summarizes the full power response capabilities of the AD816
driver. These curves apply to the differential driver applications
(right-hand side of Figure 52). In Figure 12, maximum continu­ous peak-to-peak output voltage is plotted vs. frequency for
various resistive loads. Exceeding this value on a continuous
basis can damage the AD816.

AD816

APPLICATIONS

ADSL Transceiver

The AD816 is designed for the primary purpose of providing an
integrated solution for the transmit and receive functions of an
ADSL modem. ADSL or Asymmetrical Digital Subscriber Line
is a means for delivering up to 6 Mbps from a telephone central
office (CO) into a home over the conventional telephone twisted
pair (local loop) and a few hundred kbps simultaneously in the
opposite direction.

The transmit/receive block is commonly referred to as a hybrid,
which is an old telephone term, and the function was originally
performed with passive circuitry in early phone systems. The
hybrid’s function is to deliver maximum transmit power down
the line, while providing the receive circuitry with a maximum
receive signal and a minimized (self) transmit signal. As the line
gets longer, this separation becomes much more difficult, be­cause the transmit signal must be larger to reach the other end
with acceptable SNR, while the receive signal is more attenu­ated by the longer line.

The figure of merit for the performance of the hybrid is com­monly called trans-hybrid loss and is a measure of how much
the transmit signal that appears in the receive circuit has been
attenuated relative to the amplitude of the transmit signal itself.
It is measured in dBs and is a function of frequency.

+15V

In addition to the passive circuits that have been used over time,
active circuit techniques can enhance the hybrid’s performance.
Figure 50 shows one of the various hybrid circuits that uses the
AD816 in an ADSL application. The high power op amps serve
as the transmitter, while the low noise amplifiers serve as the
receiver.

The power amplifiers of the AD816 (D1 and D2) are arranged
in a differential configuration that receives its inputs from the
differential outputs of a D/A converter. The outputs differen­tially drive the transformer primary with a turns ratio of 1:2.
The line on the secondary side of the transformer has an imped-

ance of 120 Ω. Thus one quarter of this resistance (30 Ω) is

required for back termination on the primary side due to the
impedance scaling by the square of the turns ratio. This resis-

tance is divided in half (15 Ω) and put on each side of the drive

buffers for symmetry (R101 and R201).

The receive section (R1 and R2) is configured as a pair of differ­ence amplifiers that together produce a differential output that
consists of the receive signal in addition to the transmit signal
attenuated by the trans-hybrid loss.

The circuit is highly symmetrical, so a single-ended explanation
can be easily generalized to understand the differential opera­tion. D1 output terminals (Pin 6 of the AD816) drives the top
of the primary of T1 through R101. A voltage divider is formed

by R101 and all the downstream circuitry comprised of T1, the
transmission line and its termination. For an ideal transformer,

transmission line and termination, this will appear to be 15 Ω,

and thus the signal appearing at Pins 1 and 2 of T1 will be the
output of D1 divided by two in the ideal case. This signal is
applied to the input of R1 (Receive 1 of the AD816) (Pin 3) via
R105.

In some ADSL systems (DMT), there is a need to transmit
higher crest factor signals. Typically this is done by increasing
the turns ratio of T1 to as much as 4:1. In this case, R101 and

R201 would be 3.75 Ω, and the peak current of the AD816

(1 A) would be the drive limit of the transmitter.

R1 is configured as a difference amplifier. The negative side
(Pin 2) is driven by another signal that is a divided down version
of the output of D1. This circuit is formed by R102 as one side
of the voltage divider along with R103, C101, R104 and L101
as the other half of the divider. If the frequency dependent
impedance part of this circuit matches the transformer, trans­mission line and termination impedance, then the signals
applied to both sides of the difference-amp-configured R1 will
be the same, and the transmit signal will be totally subtracted
out by the circuit.

In a real-world situation, it is not practical (or even possible) to
subtract out all of the transmit signal (100% trans-hybrid loss),
but only provide a first order cancellation which goes a long way
toward reducing the dynamic range of the RCVOUT signal.
The overall performance of this circuit depends on the ability to
build a lumped element network that matches the impedance of
the transmission line over the frequency range required for

ADSL (≈ 20 kHz to 1.1 MHz).

The circuits formed by D2 and R2 of the AD816 are totally
symmetric with those formed by D1 and R1 and work in the
same fashion. All the components in the D1, R1 circuits that are
numbered with 100 range numbers are numbered with 200
range numbers in the D2, R2 circuits.

The receive signal from the telephone line creates a differential
signal across the primary of T1. There is, however, a two to one
reduction in amplitude due to turns ratio of T1. This differen­tial signal is applied to the + inputs (Pins 3 and 12) of R1 and
R2. The receive amplifiers buffer this signal and present a differ­ential output at Pins 1 and 14. There is no significant receive
signal applied to the negative inputs of R1 and R2 due to the
attenuating effects of R101 and R201 and the low output
impedances of D1 and D2.

Thus, the overall circuit provides first order cancellation of the
transmit signal and differential buffering of the receive signal.

Dual Composite Amplifier

A composite amplifier uses two different op amps together in a
circuit to yield an overall performance that has some of the
advantages of each op amp. In the case of the AD816, two com­posite amplifiers can be constructed that offer the low noise of
the receiver amps in addition to the high current output of the
driver amps.

The circuit in Figure 51 shows an example of such a circuit. It
uses receiver amp R1 for the low noise first stage and driver D1
for the high output current second stage. Both local and overall
feedback are used to get the desired response.

Creating Differential Signals

If only a single-ended signal is available to drive the AD816 and
a differential output signal is desired, a circuit can be used to
perform the single-ended to differential conversion.

The circuit shown in Figure 52 performs this function. It uses
the AD816 with the gain of one receiver set at +1 and the gain

of the other at –1. The 1 kΩ resistor across the input terminals

of the follower makes the noise gain (NG = 2) equal to the
inverter’s. The two receiver outputs then differentially drive the
inputs to the AD816 driver with no common-mode signal to first
order.
