PRODUCT DESCRIPTION

The AD632 is an internally-trimmed monolithic four-quadrant

multiplier/divider. The AD632B has a maximum multiplying

error of

±0.5% without external trims.

Excellent supply rejection, low temperature coefficients and

long term stability of the on-chip thin film resistors and buried

zener reference preserve accuracy even under adverse condi-

tions. The simplicity and flexibility of use provide an attractive

alternative approach to the solution of complex control func-

tions.

The AD632 is pin-for-pin compatible with the industry standard

AD532 with improved specifications and a fully differential high

impedance Z-input. The AD632 is capable of providing gains of

up to X10, frequently eliminating the need for separate instru-

mentation amplifiers to precondition the inputs. The AD632

can be effectively employed as a variable gain differential input

amplifier with high common-mode rejection. The effectiveness

of the variable gain capability is enhanced by the inherent low

noise of the AD632: 90

µV rms.

PRODUCT HIGHLIGHTS

Guaranteed Performance Over Temperature

The AD632A and AD632B are specified for maximum multi-

plying errors of

±1.0% and ±0.5% of full scale, respectively at

+25

°C and are rated for operation from –25°C to +85°C.

Maximum multiplying errors of

±2.0% (AD632S) and ±1.0%

(AD632T) are guaranteed over the extended temperature range

of –55

°C to +125°C.

High Reliability

The AD632S and AD632T series are also available with

MIL-STD-883 Level B screening and all devices are available in

either the hermetically-sealed TO-100 metal can or TO-116

ceramic DIP package.
