Data Sheet Features 4-quadrant multiplication Low cost, 8-lead SOIC and PDIP packages plete- no external ponents required Laser-trimmed accuracy and stability Total error within 2% of full scale Differential high impedance X and Y inputs High impedance unity-gain summing input Laser-trimmed 10 V scaling reference APPLICATIONS Multiplication, division, squaring Modulation/demodulation, phase detection Voltage-controlled amplifiers/attenuators/filters GENERAL DESCRIPTION The AD633 is a functionally plete, 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 10 V 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 100 µV rms in a 10 Hz to 10 k Hz bandwidth. A 1 MHz bandwidth, 20 V/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 promised 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.
