GENERAL DESCRIPTION
The AD633 is a functionally complete, four-quadrant, analog
multiplier. It includes high impedance, differential X and Y inputs,
and a high impedance summing input (Z). The low impedance
output voltage is a nominal 10 V full scale provided by a buried
Zener. The AD633 is the first product to offer these features in
modestly priced 8-lead PDIP and SOIC packages.
The AD633 is laser calibrated to a guaranteed total accuracy of
2% of full scale. Nonlinearity for the Y input is typically less
than 0.1% and noise referred to the output is typically less than
100 μV rms in a 10 Hz to 10 kHz bandwidth. A 1 MHz bandwidth,
20 V/μs slew rate, and the ability to drive capacitive loads make
the AD633 useful in a wide variety of applications where
simplicity and cost are key concerns.
The versatility of the AD633 is not compromised by its
simplicity. The Z input provides access to the output buffer
amplifier, enabling the user to sum the outputs of two or more
multipliers, increase the multiplier gain, convert the output
voltage to a current, and configure a variety of applications.
The AD633 is available in 8-lead PDIP and SOIC packages. It is
specified to operate over the 0°C to 70°C commercial temperature
range (J Grade) or the −40°C to +85°C industrial temperature
range (A Grade).
PRODUCT HIGHLIGHTS
1. The AD633 is a complete four-quadrant multiplier offered
in low cost 8-lead SOIC and PDIP packages. The result is a
product that is cost effective and easy to apply.
2. No external components or expensive user calibration are
required to apply the AD633.
3. Monolithic construction and laser calibration make the
device stable and reliable.
4. High (10 MΩ) input resistances make signal source
loading negligible.
5. Power supply voltages can range from ±8 V to ±18 V. The
internal scaling voltage is generated by a stable Zener diode;
multiplier accuracy is essentially supply insensitive.

FUNCTIONAL DESCRIPTION
The AD633 is a low cost multiplier comprising a translinear
core, a buried Zener reference, and a unity-gain connected
output amplifier with an accessible summing node. Figure 1
shows the functional block diagram. The differential X and Y
inputs are converted to differential currents by voltage-to-
current converters. The product of these currents is generated
by the multiplying core. A buried Zener reference provides an
overall scale factor of 10 V. The sum of (X × Y)/10 + Z is then
applied to the output amplifier. The amplifier summing node Z
allows the user to add two or more multiplier outputs, convert
the output voltage to a current, and configure various analog
computational functions.
Inspection of the block diagram shows the overall transfer
function is

ERROR SOURCES
Multiplier errors consist primarily of input and output offsets,
scale factor error, and nonlinearity in the multiplying core. The
input and output offsets can be eliminated by using the optional
trim of Figure 10. This scheme reduces the net error to scale
factor errors (gain error) and an irreducible nonlinearity
component in the multiplying core. The X and Y nonlinearities
are typically 0.4% and 0.1% of full scale, respectively. Scale
factor error is typically 0.25% of full scale. The high impedance
Z input should always reference the ground point of the driven
system, particularly if it is remote. Likewise, the differential X
and Y inputs should reference their respective grounds to
realize the full accuracy of the AD633.

APPLICATIONS INFORMATION
The AD633 is well suited for such applications as modulation
and demodulation, automatic gain control, power measurement,
voltage-controlled amplifiers, and frequency doublers. These
applications show the pin connections for the AD633JN (8-lead
PDIP), which differs from the AD633JR (8-lead SOIC).
MULTIPLIER CONNECTIONS
Figure 11 shows the basic connections for multiplication. The X
and Y inputs normally have their negative nodes grounded, but
they are fully differential, and in many applications, the grounded
inputs may be reversed (to facilitate interfacing with signals of a
particular polarity while achieving some desired output polarity),
or both may be driven.

SQUARING AND FREQUENCY DOUBLING
As is shown in Figure 12, squaring of an input signal, E, is
achieved simply by connecting the X and Y inputs in parallel to
produce an output of E2/10 V. The input can have either polarity,
but the output is positive. However, the output polarity can be
reversed by interchanging the X or Y inputs. The Z input can be
used to add a further signal to the output.

At ωo = 1/CR, the X input leads the input signal by 45° (and is
attenuated by √2), and the Y input lags the X input by 45° (and
is also attenuated by √2). Because the X and Y inputs are 90° out of
phase, the response of the circuit is (satisfying Equation 3)

which has no dc component. Resistors R1 and R2 are included
to restore the output amplitude to 10 V for an input amplitude

The amplitude of the output is only a weak function of frequency;
the output amplitude is 0.5% too low at ω = 0.9 ω0 and ω0 = 1.1 ω0.
GENERATING INVERSE FUNCTIONS
Inverse functions of multiplication, such as division and square
rooting, can be implemented by placing a multiplier in the feedback
loop of an op amp. Figure 14 shows how to implement square
rooting with the transfer function for the condition E < 0.

VARIABLE SCALE FACTOR
In some instances, it may be desirable to use a scaling voltage
other than 10 V. The connections shown in Figure 16 increase
the gain of the system by the ratio (R1 + R2)/R1. This ratio is
limited to 100 in practical applications. The summing input, S,
can be used to add an additional signal to the output, or it can
be grounded.

LINEAR AMPLITUDE MODULATOR
The AD633 can be used as a linear amplitude modulator with
no external components. Figure 18 shows the circuit. The
carrier and modulation inputs to the AD633 are multiplied to
produce a double sideband signal. The carrier signal is fed
forward to the Z input of the AD633 where it is summed with
the double sideband signal to produce a double sideband with
the carrier output.

For example, if R = 8 kΩ and C = 0.002 µF, then Output A has a

100 mV to 10 V. Output B has an additional 0 at 10 kHz (and
can be loaded because it is the low impedance output of the
multiplier). The circuit can be changed to a high-pass filter Z

VOLTAGE-CONTROLLED QUADRATURE OSCILLATOR
Figure 21 shows two multipliers being used to form integrators
with controllable time constants in second-order differential
equation feedback loop. R2 and R5 provide controlled current
output operation. The currents are integrated in capacitors C1
and C2, and the resulting voltages at high impedance are applied
to the X inputs of the next AD633. The frequency control input,
EC, connected to the Y inputs, varies the integrator gains with a
calibration of 100 Hz/V. The accuracy is limited by the Y input
offsets. The practical tuning range of this circuit is 100:1. C2
(proportional to C1 and C3), R3, and R4 provide regenerative
feedback to start and maintain oscillation. The diode bridge, D1
through D4 (1N914s), and Zener diode D5 provide economical
temperature stabilization and amplitude stabilization at ±8.5 V
by degenerative damping. The output from the second integrator
(10 V sin ωt) has the lowest distortion.
AUTOMATIC GAIN CONTROL (AGC) AMPLIFIERS
Figure 22 shows an AGC circuit that uses an rms-to-dc
converter to measure the amplitude of the output waveform.
The AD633 and A1, ½ of an AD712 dual op amp, form a
voltage-controlled amplifier. The rms-to-dc converter, an
AD736, measures the rms value of the output signal. Its output
drives A2, an integrator/comparator whose output controls the
gain of the voltage-controlled amplifier. The 1N4148 diode
prevents the output of A2 from going negative. R8, a 50 kΩ
variable resistor, sets the output level of the circuit. Feedback
around the loop forces the voltages at the inverting and
noninverting inputs of A2 to be equal, thus the AGC.
