GENERAL DESCRIPTION
The AD633-EP 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-EP is available in an 8-lead SOIC package. It is
specified to operate over the −55°C to +125°C military
temperature range.
The AD633-EP 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-EP useful in a wide variety of applications where
simplicity and cost are key concerns.
PRODUCT HIGHLIGHTS
The versatility of the AD633-EP 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. For further information,
see the Multiplier Application Guide.

The AD633-EP is a complete four-quadrant multiplier
offered in a low cost 8-lead SOIC package. The result is a
product that is cost effective and easy to apply.
No external components or expensive user calibration are
required to apply the AD633-EP.
Monolithic construction and laser calibration make the
device stable and reliable.
High (10 MΩ) input resistances make signal source
loading negligible.
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.

ABSOLUTE MAXIMUM RATINGS
THERMAL RESISTANCE
For supply voltages less than ±18 V, the absolute maximum input voltage is
equal to the supply voltage.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
Thermal performance is directly linked to printed circuit board
(PCB) design and operating environment. Careful attention to
PCB thermal design is required.
