PRODUCT 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 plastic DIP 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 AD633’s versatility 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 an 8-lead plastic DIP package (N)

and 8-lead SOIC (R). 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 plastic 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.
