The AD632 is an internally-trimmed monolithic four-quadrant multiplier/divider from Analog Devices. It has a maximum multiplying error of ±0.5% without external trims. The product features excellent supply rejection, low temperature coefficients and long term stability, even under adverse conditions. 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 instrumentation amplifiers to precondition the inputs. The AD632 can be effectively employed as a variable gain divider.
