AD633 Four-Quadrant Analog Multiplier

Analog Devices AD633 Four-Quadrant Analog Multiplier includes high impedance, differential X and Y inputs, and a high impedance summing input (Z). The low impedance output voltage is a nominal 10V full scale provided by a buried Zener. The AD633 is the first product to offer these features in modestly priced 8-lead PDIP and SOIC packages. The AD633 is laser calibrated to a guaranteed total accuracy of 2% of full scale. Nonlinearity for the Y input is typically less than 0.1%, and noise referred to the output is typically less than 100μV_rms in a 10Hz to 10kHz bandwidth. A 1MHz bandwidth, 20V/μs slew rate, and the ability to drive capacitive loads make the AD633 useful in a wide variety of applications where simplicity and cost are key concerns.
