Multiplication, division, squaring Modulation/demodulation, phase detection Voltage-controlled amplifiers/attenuators/filters FUNCTIONAL BLOCK DIAGRAM A 10V 00786-023 W Z Figure 1. GENERAL DESCRIPTION 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 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 kHz 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 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. The AD633 is available in 8-lead PDIP and SOIC packages. It 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). PRODUCT HIGHLIGHTS 1. The AD633 is a complete four-quadrant multiplier offered in low cost 8-lead SOIC and PDIP packages. The result is a product that is cost effective and easy to apply. 2. No external components or expensive user calibration are required to apply the AD633. 3. Monolithic construction and laser calibration make the device stable and reliable. 4. High (10 MΩ) input resistances make signal source loading negligible. 5. Power supply voltages can range from ±8 V to ±18 V. T h e internal scaling voltage is generated by a stable Zener diode; multiplier accuracy is essentially supply insensitive. Rev.

1 For supply voltages less than ±18 V, the absolute maximum input voltage is
equal to the supply voltage. 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 RESISTANCE θJA is specified for the worst-case conditions, that is, a device soldered in a circuit board for surface-mount packages. Table 3.
