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-EP is available in an 8-lead SOIC package. It is specified to operate over the -55C to +125C military temperature range. 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 100 V rms in a 10 Hz to 10 kHz bandwidth. A 1 MHz bandwidth, 20 V/s slew rate, and the ability to drive capacitive loads make the AD633-EP useful in a wide variety of applications where simplicity and cost are key concerns. PRODUCT HIGHLIGHTS The versatility of the AD633-EP 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. For further information, see the Multiplier Application Guide. Rev. B Additional application and technical information can be found in the AD633 data sheet. 1. 2. 3. 4. 5. The AD633-EP is a complete four-quadrant multiplier offered in a low cost 8-lead SOIC package. The result is a product that is cost effective and easy to apply. No external components or expensive user calibration are required to apply the AD633-EP. Monolithic construction and laser calibration make the device stable and reliable. High (10 M) input resistances make signal source loading negligible. Power supply voltages can range from 8 V to 18 V. The internal scaling voltage is generated by a stable Zener diode; multiplier accuracy is essentially supply insensitive.

Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Thermal performance is directly linked to printed circuit board (PCB) design and operating environment. Careful attention to PCB thermal design is required. Table 3.
