The AD632 is an internally trimmed monolithic four-quadrant multiplier/divider. It features pretrimmed to ±0.5% maximum 4-quadrant error, differential, high impedance inputs, adjustable scale factor for up to ×10 gain, low noise design, and low cost monolithic construction. It is suitable for high-quality analog signal processing, differential ratio and percentage computations, algebraic and trigonometric function synthesis, and accurate voltage controlled oscillators and filters.
