The AD633-EP is a functional y complete, four-quadrant, analog The AD633-EP is available in an 8-lead SOIC package. It is multiplier. It includes high impedance, differential X and Y inputs, specified to operate over the −55°C to +125°C military and a high impedance summing input (Z). The low impedance temperature range. output voltage is a nominal 10 V full scale provided by a buried Additional application and technical information can be found Zener. in the AD633 data sheet. The AD633-EP 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 1. The AD633-EP is a complete four-quadrant multiplier 100 µV rms in a 10 Hz to 10 kHz bandwidth. A 1 MHz bandwidth, offered in a low cost 8-lead SOIC package. The result is a 20 V/µs slew rate, and the ability to drive capacitive loads make product that is cost effective and easy to apply. the AD633-EP useful in a wide variety of applications where 2.
