ADI AD633ARZ

The AD633 is a functionally complete, four - quadrant, analog multiplier. It 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. The versatility of the AD633 is not compromised by its simplicity. The Z input provides access to the output buffer amplifier, enabling the user to sum the outputs of two or more multipliers, increase the multiplier gain, convert the output voltage to a current, and configure a variety of applications.
