DESCRIPTION

· The AD632 is an internally trimmed monolithic four-quadrant multiplier/divider.

· It offers a maximum multiplying error of ±0.5% without external trims.

· Features excellent supply rejection, low temperature coefficients, and long-term stability.

· Pin-for-pin compatible with the AD532, with improved specifications and a fully differential high impedance Z input.

· Capable of providing gains up to ×10, reducing the need for separate instrumentation amplifiers.

FEATURES

· Pretrimmed to ±0.5% maximum 4-quadrant error.

· All inputs (X, Y, and Z) are differential and high impedance.

· Scale-factor adjustable to provide up to ×10 gain.

· Low noise design: 90 mV rms, 10 Hz to 10 kHz.

· Low cost, monolithic construction with excellent long-term stability.

APPLICATIONS

· High-quality analog signal processing.

· Differential ratio and percentage computations.

· Algebraic and trigonometric function synthesis.

· Accurate voltage-controlled oscillators and filters.

· Effective as a variable gain differential input amplifier with high common-mode rejection.
