Overview
The AD734BNZ, produced by Analog Devices Inc., is a high-accuracy, high-speed, four-quadrant analog multiplier/divider. It is pin-compatible with the industry-standard AD534 and provides the transfer function W = XY/U. This component is designed to offer low impedance voltage output with a full-power bandwidth of 10 MHz and a slew rate of 450 V/µs. The AD734BNZ is particularly noted for its high accuracy, with a total static error of 0.1% of full scale, and its low distortion, typically less than -80 dBc from any input. It is suitable for a wide range of applications requiring precise analog signal processing.
