AD632AD

The AD632AD is an internally trimmed precision monolithic four-quadrant multiplier/divider from Analog Devices. It features fully differential high-impedance X, Y, and Z inputs and implements the transfer function [(X1-X2)(Y1-Y2)/10] + Z2. The device is pretrimmed to achieve a maximum 4-quadrant error of ±0.5% at +25°C without external components.

Key electrical specifications include a typical bandwidth of 1 MHz, supply voltage range of 16V to 44V, typical supply current of 6 mA, input voltage range of ±12V, and output voltage range of ±11V. The low noise design achieves 90 µV rms over 10 Hz to 10 kHz. The AD632 is pin-for-pin compatible with the industry standard AD532 but offers improved specifications and a fully differential Z input.

Typical applications include high quality analog signal processing, differential ratio and percentage computations, algebraic and trigonometric function synthesis, and accurate voltage controlled oscillators and filters. The device is suitable for designs requiring high accuracy, low drift, and long-term stability.

The AD632AD is packaged in a 14-lead side brazed CerDIP (CDIP) with 0.300" (7.62 mm) lead spacing, intended for through-hole mounting. The operating temperature range is -25°C to +85°C for the A and B grades. The product status is active and suitable for new designs.
