AD633TRZ-EP-R7

Overview

The AD633TRZ-EP-R7 is a four-quadrant analog multiplier in an 8-lead SOIC package. It features high impedance differential X and Y inputs, a high impedance summing input (Z), and a low impedance output voltage with a nominal 10 V full scale provided by a buried Zener reference. The device operates over a military temperature range of −55°C to +125V. 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 typical at ±15 V. Total error is guaranteed within ±2% of full scale at 25°C and ±3% across the operating temperature range.

Feature Summary

• Supports defense and aerospace applications through AQEC standard compliance.
• Laser-trimmed accuracy ensures total error remains within specified limits without external calibration.
• Monolithic construction provides stability and reliability for demanding environments.
• High input resistance minimizes signal source loading effects.

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 suffix configuration for tape and reel packaging. Confirm that the enhanced product designation aligns with project requirements for controlled manufacturing baselines and single assembly sites. Ensure compatibility with the specified military temperature range and RoHS compliance status before finalizing procurement documentation.

Selection Notes

Select this component when a functionally complete four-quadrant multiplier is needed without external calibration components. The device is suitable for applications requiring high input impedance and stable scaling references. Consider the 8-lead SOIC package constraints and thermal dissipation characteristics relative to the PCB design. Verify that the power supply voltages fall within the rated operating range of ±8 V to ±18 V.

Part Context

This component belongs to the AD633-EP Enhanced Product line from Analog Devices. It is designed specifically for defense and aerospace sectors, adhering to strict quality standards. The device shares functional similarities with the commercial AD633 but offers extended temperature capabilities and controlled production processes. It serves as a cost-effective solution for precision analog computation tasks.

Replacement Considerations

The AD633TRZ-EP is the direct replacement for the AD633TRZ-EP-R7 variant within the same reel specification. Both share identical electrical specifications and pinouts. Ensure that any substitute maintains the enhanced product qualifications if military or aerospace usage is required.
