The AD633 is a functionally complete, four-quadrant, analog The AD633 is available in 8-lead PDIP and SOIC packages. It is multiplier. It includes high impedance, differential X and Y inputs, specified to operate over the 0°C to 70°C commercial temperature and a high impedance summing input (Z). The low impedance range (J Grade) or the −40°C to +85°C industrial temperature output voltage is a nominal 10 V ful scale provided by a buried range (A Grade). Zener. The AD633 is the first product to offer these features in
PRODUCT HIGHLIGHTS
modestly priced 8-lead PDIP and SOIC packages. 1. The AD633 is a complete four-quadrant multiplier offered The AD633 is laser calibrated to a guaranteed total accuracy of in low cost 8-lead SOIC and PDIP packages. The result is a 2% of full scale. Nonlinearity for the Y input is typically less product that is cost effective and easy to apply. than 0.1% and noise referred to the output is typically less than 2. No external components or expensive user calibration are 100 µV rms in a 10 Hz to 10 kHz bandwidth. A 1 MHz bandwidth, required to apply the AD633. 20 V/µs slew rate, and the ability to drive capacitive loads make 3. Monolithic construction and laser calibration make the the AD633 useful in a wide variety of applications where device stable and reliable. simplicity and cost are key concerns. 4. High (10 MΩ) input resistances make signal source The versatility of the AD633 is not compromised by its simplicity. loading negligible. The Z input provides access to the output buffer amplifier, enabling 5. Power supply voltages can range from ±8 V to ±18 V. The the user to sum the outputs of two or more multipliers, increase internal scaling voltage is generated by a stable Zener diode; the multiplier gain, convert the output voltage to a current, and multiplier accuracy is essentially supply insensitive. configure a variety of applications.
