AD734SQ/883B

Overview

The AD734SQ/883B is a high-speed, four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. Processed to MIL-STD-883B standards, it operates within the military temperature range of −55°C to +125°C and utilizes a 14-lead CERDIP package. The device provides a transfer function of W = XY/U with a full power bandwidth of 10 MHz and a typical total static error of 0.1%. It features a low impedance voltage output, fully differential X, Y, and Z inputs, and an internal scaling denominator voltage of 10 V derived from a buried-Zener reference.

Feature Summary

• High accuracy with 0.1% typical total static error across the operating temperature range
• High speed performance featuring a 10 MHz full power bandwidth and 450 V/μs slew rate
• Low distortion characteristics with guaranteed -80 dBc distortion from any input
• Direct division mode capability allowing external control of the denominator voltage

Applications

• High performance replacement for AD534
• Modulators and demodulators
• Wideband gain control and rms-to-dc conversion
• Voltage-controlled amplifiers, oscillators, and filters

Procurement Notes

Verify that the specific ordering suffix /883B confirms compliance with MIL-STD-883B processing requirements. Confirm the package type is strictly 14-lead CERDIP. Ensure the component meets the specified military temperature range of −55°C to +125°C before integration into sensitive applications.

Selection Notes

Select this component when military-grade reliability and extended temperature operation are required. It serves as a pin-compatible upgrade to the AD534, offering superior dynamic response and lower distortion. Consider the direct denominator control feature if precise two-quadrant division or variable scaling is necessary for the design.

Part Context

The AD734 series includes variants such as the AD734AQ and AD734BQ for industrial temperatures (-40°C to +85°C). The AD734SQ/883B is specifically processed to meet MIL-STD-883B standards for the military temperature range (-55°C to +125°C) and is available exclusively in a 14-lead CERDIP package.

Replacement Considerations

The AD734 is pin compatible with the industry-standard AD534. It can be substituted directly in many applications to improve static accuracy, distortion, feedthrough, and speed.
