DESCRIPTION

The MPY634 is a wide bandwidth, high accuracy, four­quadrant analog multiplier. Its accurately laser-trimmed
multiplier characteristics make it easy to use in a wide
variety of applications with a minimum of external parts,
often eliminating all external trimming. Its differential X, Y,
and Z inputs allow configuration as a multiplier, squarer,
divider, square-rooter, and other functions while maintain­ing high accuracy.

The wide bandwidth of this new design allows signal
processing at IF, RF, and video frequencies. The internal
output amplifier of the MPY634 reduces
design complexity compared to other high frequency mul­tipliers and balanced modulator circuits. It is
capable of performing frequency mixing, balanced modula­tion, and demodulation with excellent carrier rejection.

An accurate internal voltage reference provides
precise setting of the scale factor. The differential Z input
allows user-selected scale factors from 0.1 to 10 using
external feedback resistors.

THEORY OF OPERATION

The transfer function for the MPY634 is:

V

OUT

where:

A = open-loop gain of the output amplifier (typically

85dB at DC).

SF = Scale Factor. Laser-trimmed to 10V but adjustable

over a 3V to 10V range using external resistors.

X, Y, Z are input voltages. Full-scale input voltage
is equal to the selected SF. (Max input voltage =
±1.25 SF).

An intuitive understanding of transfer function can be gained
by analogy to the op amp. By assuming that the open-loop
gain, A, of the output operational amplifier is infinite,

MPY634

SBFS017A

(X1 – X2) (Y1 – Y2)

= A – (Z1 – Z2)

SF

www.ti.com

inspection of the transfer function reveals that any V

OUT

can
be created with an infinitesimally small quantity within the
brackets. Then, an application circuit can be analyzed by
assigning circuit voltages for all X, Y and Z inputs and
setting the bracketed quantity equal to zero. For example,
the basic multiplier connection in Figure 1, Z1 = V

OUT

and

Z2 = 0. The quantity within the brackets then reduces to:

(X1 – X2) (Y1 – Y2)

– (V

SF

OUT

– 0) = 0

This approach leads to a simple relationship which can be
solved for V

to provide the closed-loop transfer function.

OUT

The scale factor is accurately factory adjusted to 10V and is
typically accurate to within 0.1% or less. The scale factor
may be adjusted by connecting a resistor or potentiometer
between pin SF and the –VS power supply. The value of the
external resistor can be approximated by:

5

RSF = 5.4kΩ

SF

10 – SF

Internal device tolerances make this relationship accurate to
within approximately 25%. Some applications can benefit
from reduction of the SF by this technique. The reduced
input bias current, noise, and drift achieved by this technique
can be likened to operating the input circuitry in a higher
gain, thus reducing output contributions to these effects.
Adjustment of the scale factor does not affect bandwidth.

The MPY634 is fully characterized at V

= ±15V but

S

operation is possible down to ±8V with an attendant reduc­tion of input and output range capability. Operation at
voltages greater than ±15V allows greater output swing to be
achieved by using an output feedback attenuator (Figure 1).

As with any wide bandwidth circuit, the power supplies
should be bypassed with high frequency ceramic capacitors.
These capacitors should be located as near as practical to the
power supply connections of the MPY634. Improper by­passing can lead to instability, overshoot, and ringing in the
output.

BASIC MULTIPLIER CONNECTION

Figure 2 shows the basic connection as a multiplier. Accu­racy is fully specified without any additional user-trimming
circuitry. Some applications can benefit from trimming of
one or more of the inputs. The fully differential inputs
facilitate referencing the input quantities to the source volt­age common terminal for maximum accuracy. They also
allow use of simple offset voltage trimming circuitry as
shown on the X input.

The differential Z input allows an offset to be summed in
V

. In basic multiplier operation, the Z2 input serves as

OUT

the output voltage ground reference and should be connected
to the ground of the driven system for maximum accuracy.

A method of changing (lowering) SF by connecting to the
SF pin was discussed previously. Figure 1 shows an alterna­tive method of changing the effective SF of the overall
circuit by using an attenuator in the feedback connection to
Z1. This method puts the output amplifier in a higher gain
and is thus accompanied by a reduction in bandwidth and an

may be reduced by applying a trimming voltage to the high
impedance input, Z

.

The flexibility of the differential Z inputs allows direct
conversion of the output quantity to a current. Figure 3
shows the output voltage differentially-sensed across a se­ries resistor forcing an output-controlled current. Addition
of a capacitor load then creates a time integration function
useful in a variety of applications such as power computa­tion.

SQUARER CIRCUIT (FREQUENCY DOUBLER)

Squarer, or frequency doubler, operation is achieved by
paralleling the X and Y inputs of the standard multiplier
circuit. Inverted output can be achieved by reversing the
differential input terminals of either the X or Y input.
Accuracy in the squaring mode is typically a factor of two
better than the specified multiplier mode with maximum
error occurring with small (less than 1V) inputs. Better
accuracy can be achieved for small input voltage levels by
reducing the scale factor, SF.

DIVIDER OPERATION

The MPY634 can be configured as a divider as shown in
Figure 4. High impedance differential inputs for the numera­tor and denominator are achieved at the Z and X inputs,

respectively. Feedback is applied to the Y2 input, and Y1 is

g

normally referenced to output ground. Alternatively, as the
transfer function implies, an input applied to Y1 can be
summed directly into V

. Since the feedback connection

OUT

is made to a multiplying input, the effective gain of the
output op amp varies as a function of the denominator input
voltage. Therefore, the bandwidth of the divider function is
proportional to the denominator voltage (see Typical Perfor­mance Curves).

FIGURE 4. Basic Divider Connection.

Accuracy of the divider mode typically ranges from 1.0% to

2.5% for a 10 to 1 denominator range depending on device
grade. Accuracy is primarily limited by input offset voltages
and can be significantly improved by trimming the offset of
the X input. A trim voltage of ±3.5mV applied to the “low
side” X input (X2 for positive input voltages on X1) can
produce similar accuracies over 100 to 1 denominator range.
To trim, apply a signal which varies from 100mV to 10V at
a low frequency (less than 500Hz). An offset sine wave or
ramp is suitable. Since the ratio of the quantities should be
constant, the ideal output would be a constant 10V. Using
AC coupling on an oscilloscope, adjust the offset control for
minimum output voltage variation.

SQUARE-ROOTER

A square-rooter connection is shown in Figure 5. Input
voltage is limited to one polarity (positive for the connection
shown). The diode prevents circuit latch-up should the input
go negative. The circuit can be configured for negative input
and positive output by reversing the polarity of both the X
and Y inputs. The output polarity can be reversed by revers­ing the diode and X input polarity. A load resistance of
approximately 10kΩ must be provided. Trimming for im­proved accuracy would be accomplished at the Z input.

By injecting the input carrier signal into the output through connection
to the Z

input, conventional amplitude modulation is achieved.

Amplification can be achieved by use of the SF pin, or Z attenuator
(at the expense of bandwidth).

The basic muliplier connection performs balanced modulation.
Carrier rejection can be improved by trimming the offset voltage
of the modulation input. Better carrier rejection above 2MHz is
typically achieved by interchanging the X and Y inputs (carrier
applied to the X input).

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability

information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that

lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
