General Description
The EL2020 is a fast settling, wide bandwidth amplifier optimized for gains between
monolithic Complementary Bipolar process, this amplifier uses
current mode feedback to achieve more bandwidth at a given
gain then a conventional voltage feedback operational amplifier.
The EL2020 will drive two double terminated 75X coax cables
to video levels with low distortion. Since it is a closed loop device, the EL2020 provides better gain accuracy and lower distortion than an open loop buffer. The device includes output short
circuit protection, and input offset adjust capability.
The bandwidth and slew rate of the EL2020 are relatively independent of the closed loop gain taken. The 50 MHz bandwidth
at unity gain only reduces to 30 MHz at a gain of 10. The
EL2020 may be used in most applications where a conventional
op amp is used, with a big improvement in speed power product.

Application Information
Theory of Operation
The EL2020 has a unity gain buffer similar to the
EL2003 from the non-inverting input to the inverting input. The error signal of the EL2020 is a
current flowing into (or out of) the inverting input. A very small change in current flowing
through the inverting input will cause a large
change in the output voltage. This current amplification is the transresistance (R

Resistor Value Selection and
Optimization
The value of the feedback resistor (and an internal capacitor) sets the AC dynamics of the
EL2020. A nominal value for the feedback resistor is 1 kX, which is the value used for production testing. This value guarantees stability. For
a given gain, the bandwidth may be increased by
decreasing the feedback resistor and, conversely,
the bandwidth will be decreased by increasing
the feedback resistor.
Reducing the feedback resistor too much will result in overshoot and ringing, and eventually oscillations. Increasing the feedback resistor results

Input Range
The non-inverting input to the EL2020 looks like
a high resistance in parallel with a few picofarads
in addition to a DC bias current. The input characteristics change very little with output loading,
even when the amplifier is in current limit.
pling. Inductive sources may cause oscillations; a
1kXresistor in series with the input lead will
usually eliminate problems without sacrificing
too much speed.
Current Limit
The EL2020 has internal current limits that protect the output transistors. The current limit
goes down with junction temperature rise. At a
junction temperature of
a
175§C the current limits are at about 50 mA. If the EL2020 output is
shorted to ground when operating on
g
15V sup-
plies, the power dissipation could be as great as
1.1W. A heat sink is required in order for the
EL2020 to survive an indefinite short. Recovery
time to come out of current limit is about 50 ns.
Using the 2020 with Output Buffers
When more output current is required, a wideband buffer amplifier can be included in the feedback loop of the EL2020. With the EL2003 the
subsystem overshoots about 10% due to the
phase lag of the EL2003. With the EL2004 in the
loop, the overshoot is less than 2%. For even
more output current, several buffers can be paralleled.
EL2020 Buffered with an EL2004
The input charactersitics also change when the
input voltage exceeds either supply by 0.5V. This
happens because the input transistor’s base-collector junctions forward bias. If the input exceeds
the supply by LESS than 0.5V and then returns
to the normal input range, the output will recover in less than 10 ns. However if the input exceeds the supply by MORE than 0.5V, the recovery time can be 100’s of nanoseconds. For this
reason it is recommended that Schottky diode
clamps from input to supply be used if a fast recovery from large input overloads is required.
Source Impedance
The EL2020 is fairly tolerant of variations in
source impedances. Capacitive sources cause no
problems at all, resistive sources up to 100 kX
present no problems as long as care is used in
board layout to minimize output to input cou-
2020– 13
Capacitive Loads
The EL2020 is like most high speed feedback amplifiers in that it does not like capacitive loads
between 50 pF and 1000 pF. The output resistance works with the capacitive load to form a
second non-dominate pole in the loop. This results in excessive peaking and overshoot and can
lead to oscillations. Standard resistive isolation
techniques used with other op amps work well to
isolate capacitive loads from the EL2020.

Compensation
The EL2020 is internally compensated to work
with external feedback resistors for optimum
bandwidth over a wide range of closed loop gain.
The part is designed for a nominal 1 kX of feedback resistance, although it is possible to get
more bandwidth by decreasing the feedback resistance.
The EL2020 becomes less stable by adding capacitance in parallel with the feedback resistor,
so feedback capacitance is not recommended.
The EL2020 is also sensitive to stray capacitance
from the inverting input to ground, so the board
should be laid out to keep the physical size of this
node small, with ground plane kept away from
this node.
Active Filters
The EL2020’s low phase lag at high frequencies
makes it an excellent choice for high performance
active filters. The filter response more closely approaches the theoritical response than with conventional op amps due to the EL2020’s smaller
propagation delay. Because the internal compensation of the EL2020 depends on resistive feedback, the EL2020 should be set up as a gain
block.
Driving Cables
The EL2020 was designed with driving coaxial
cables in mind. With 30 mA of output drive and
low output impedance, driving one to three 75X
double terminated coax cables with one EL2020
is practical. Since it is easy to set up a gain of
a
2, the double matched method is the best way
to drive coax cables, because the impedance
match on both ends of the cable will suppress
reflections. For a discussion on some of the other
ways to drive cables, see the section on driving
cables in the EL2003 data sheet.
Video Performance Characteristics
The EL2020 makes an excellent gain block for
video systems, both RS-170 (NTSC) and faster.
It is capable of driving 3 double terminated 75X
cables with distortion levels acceptable to broadcasters. A common video application is to drive a
75X double terminated coax with a gain of 2.
To measure the video performance of the EL2020
in the non-inverting gain of 2 configuration, 5
identical gain-of-two circuits were cascaded (with
a divide by two 75X attenuator between each
stage) to increase the errors.
The results, shown in the photos, indicate the entire system of 5 gain-of-two stages has a differential gain of 0.5% and a differential phase of 0.5
This implies each device has a differential
gain/phase of 0.1% and 0.1

EL2020 Disable/Enable Operation
The EL2020 has an enable/disable control input
at pin 8. The device is enabled and operates normally when pin 8 is left open or returned to pin 7,
V
. When more than 250 mA is pulled from pin
CC
8, the EL2020 is disabled. The output becomes a
high impedance, the inverting input is no longer
driven to the positive input voltage, and the supply current is halved. To make it easy to use this
feature, there is an internal resistor to limit the
current to a safe level (E1.1 mA) if pin 8 is
grounded.
Using the EL2020 as a Multiplexer
An interesting use of the enable feature is to combine several amplifiers in parallel with their outputs common. This combination then acts similar to a MUX in front of an amplifier. A typical
circuit is shown.
When the EL2020 is disabled, the DC output impedance is very high, over 10 kX. However there
is also an output capacitance that is non-linear.
For signals of less than 5V peak to peak, the output capacitance looks like a simple 15 pF capacitor. However, for larger signals the output capacitance becomes much larger and non-linear.
The example multiplexer will switch between
amplifiers in 5 ms for signals of less than
the outputs. For full output signals of 20V peak
to peak, the selection time becomes 25 ms. The
disabled outputs also present a capacitive load
and therefore only three amplifiers can have their
outputs shorted together. However an unlimited
number can sum together if a small resistor
(25X) is inserted in series with each output to
isolate it from the ‘‘bus’’. There will be a small
gain loss due to the resistors of course.
Using the EL2020 as a Multiplexer
g
2V on
To draw current out of pin 8 an ‘‘open collector
output’’ logic gate or a discrete NPN transistor
can be used. This logic interface method has the
advantage of level shifting the logic signal from
5V supplies to whatever supply the EL2020 is operating on without any additional components.
