AD746SQ

Instrumentation, Op Amps, Buffer Amps Overview

The AD746SQ is a dual precision BiFET operational amplifier manufactured by Analog Devices Inc. It features a 500 ns settling time to 0.01% for a 10 V step, a 75 V/µs slew rate, and a 13 MHz gain bandwidth product. The device offers a maximum input offset voltage of 0.5 mV and operates within a supply range of ±4.5 V to ±18 V. It is processed to MIL-STD-883B standards and housed in an 8-pin Cerdip package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Internal compensation ensures stable operation as a unity gain inverter or noninverting amplifier with gains of two or greater.
• Monolithic construction provides close matching of AC and DC characteristics between the two amplifiers on the same die.
• Laser wafer drift trimming and ion-implanted JFETs deliver high DC precision and low noise performance.

Instrumentation, Op Amps, Buffer Amps Applications

• Dual output buffers for 12-bit and 14-bit DACs
• Input buffers for precision ADCs
• Wideband preamplifiers
• Low distortion audio circuitry

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the component is processed to MIL-STD-883B Rev. C standards as indicated by the SQ suffix. Confirm the package type is hermetic Cerdip (Q-8). Ensure the part number matches the specific military grade requirements for your application.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this model when military-grade reliability and hermetic sealing are required. It is suitable for applications demanding fast settling times and high DC precision. Consider the AD746J or AD746A for commercial or industrial temperature ranges if MIL-STD processing is not necessary.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD746SQ belongs to the AD746 family of dual precision BiFET op amps. It shares the same monolithic die architecture as the AD746J and AD746A but is distinguished by its military qualification and hermetic Cerdip packaging. This variant is designed for environments requiring strict adherence to aerospace and defense specifications.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements include other AD746 variants such as AD746JN or AD746AQ, provided the temperature range and package style meet the design requirements. Verify pinout compatibility and electrical specifications before substitution.
