AD633 – Analog Multiplier IC SMD

AD633 – Analog Multiplier IC SMD

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 10 V full scale provided by a buried Zener. The AD633 is the first product to offer these features in modestly priced 8-lead plastic DIP and SOIC packages.
The AD633 is laser calibrated to a guaranteed total accuracy of 2% of full scale. Non-linearity for the Y-input is typically less than 0.1% and noise referred to the output is typically less than 100 mV rms in a 10 Hz to 10 kHz bandwidth. A 1 MHz bandwidth, 20 V/ms 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 AD633’s versatility 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.
The AD633 is specified to operate over the 0°C to +70°C commercial temperature range (J Grade) or the –40°C to +85°C industrial temperature range (A Grade).
