GENERAL 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 conditions.
The simplicity and flexibility of use provide an attractive alternative
approach to the solution of complex control functions.
The AD632 is pin-for-pin compatible with the industry
standard AD532 but with improved specifications and a fully
differential high impedance Z input. The AD632 is capable of
providing gains of up to ×10, frequently eliminating the need
for separate instrumentation 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 at 90 µV rms.
PRODUCT HIGHLIGHTS
1. Guaranteed performance over temperature.
2. The AD632A and AD632B are specified for maximum
multiplying 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.
3. Maximum multiplying errors of ±2.0% (AD632S) and
±1.0% (AD632T) are guaranteed over the extended
temperature range of −55°C to +125°C.
4. High reliability.
5. The AD632S and AD632T series are available with MIL-
STD-883 Level B screening.
6. All devices are available in either the hermetically sealed
TO-100 metal can or ceramic DIP package.
