AD633JR

Overview

The AD633JR is a four-quadrant analog multiplier in an 8-lead SOIC package. It performs multiplication with a nominal 10 V full-scale output derived from a buried Zener reference. The device features high-impedance differential X and Y inputs and a high-impedance summing input (Z). Key electrical parameters include a small-signal bandwidth of 1 MHz, a slew rate of 20 V/µs, and a quiescent supply current of 4 mA. It operates on dual supplies ranging from ±8 V to ±18 V and is specified for the commercial temperature range of 0°C to 70°C.

Feature Summary

• Laser-trimmed accuracy ensuring total error remains within 2% of full scale.
• Complete design requiring no external components or expensive user calibration.
• High input resistance of 10 MΩ minimizes signal source loading.
• Monolithic construction provides stability and reliability.

Applications

• Multiplication, division, and squaring operations
• Modulation and demodulation circuits
• Phase detection systems
• Voltage-controlled amplifiers, attenuators, and filters

Procurement Notes

Verify that the specific orderable part number matches the required package type and temperature grade. Confirm that the suffix indicates the correct reel or tube packaging configuration if applicable. Ensure the component meets RoHS compliance standards relevant to your manufacturing region. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and updated specifications before finalizing procurement.

Selection Notes

Select this component when a cost-effective, complete analog multiplier solution is required without external calibration. The 8-lead SOIC package is suitable for surface-mount applications where space is limited. Consider the 1 MHz bandwidth and 20 V/µs slew rate for mid-frequency signal processing tasks. Verify that the operating temperature range aligns with the commercial specification limits of the application environment.

Part Context

The AD633 series represents a family of low-cost, functionally complete analog multipliers available in both PDIP and SOIC packages. The AD633JR specifically denotes the industrial-grade version in the SOIC-8 format, though the provided documentation specifies the commercial temperature range for the J grade. This component is designed for applications prioritizing simplicity and cost-efficiency over extreme precision.

Replacement Considerations

Direct replacements must maintain the four-quadrant multiplication capability and 8-lead SOIC footprint. Verify pinout compatibility, particularly regarding the differential X and Y inputs and the summing Z input. Ensure the replacement supports the same supply voltage range and offers comparable bandwidth and accuracy specifications.
