Overview
The AD734ANZ is a high-speed, four-quadrant analog multiplier/divider produced by Analog Devices Inc. It is pin-compatible with the industry-standard AD534 and provides the transfer function W = XY/U. This component is designed for high accuracy and low distortion, making it suitable for a wide range of applications. The AD734ANZ offers a low-impedance voltage output with a full-power bandwidth of 10 MHz and a total static error of 0.1% of full scale. It features a high slew rate of 450 V/μs and a settling time of 200 ns to 0.1% at full power.
