AD8692ARZ

Overview

The AD8692ARZ is a dual-channel, low-cost, low-noise CMOS operational amplifier with rail-to-rail output. It operates on a single supply voltage ranging from 2.7 V to 6 V and is unity-gain stable. The device features a typical offset voltage of 400 µV with a maximum drift of 6 µV/°C. Input bias current is limited to 1 pA maximum, while the voltage noise density is 8 nV/√Hz at 1 kHz. The gain bandwidth product is 10 MHz, and the slew rate is 5 V/µs. It is specified over an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Rail-to-rail output capability for maximizing dynamic range in single-supply applications
• Very low input bias currents suitable for high-impedance sensor interfaces
• Low offset voltage and drift characteristics ensuring DC precision
• Wide signal bandwidth combined with low distortion for AC performance

Applications

• Photodiode amplification
• Battery-powered instrumentation
• Medical instruments
• Multipole filters
• Portable audio devices

Procurement Notes

Verify that the component matches the specific package option (8-Lead SOIC_N) and RoHS compliance indicated by the suffix. Confirm the operating temperature range requirements align with the specified −40°C to +125°C limits. Ensure supply voltage constraints between 2.7 V and 6 V are met within the target circuit design parameters.

Selection Notes

Select this component when a dual-channel configuration is required alongside rail-to-rail output swing. It is appropriate for designs needing low offset voltage and very low input bias currents. Consider its 10 MHz bandwidth and 5 V/µs slew rate for moderate-speed signal processing tasks requiring high DC accuracy.

Part Context

This part belongs to the AD869x family of low-cost, low-noise CMOS operational amplifiers manufactured by Analog Devices. The family includes single-channel (AD8691), dual-channel (AD8692), and quad-channel (AD8694) variants. All members share similar electrical characteristics but differ in channel count and package options.

Replacement Considerations

Direct functional substitutes within the same family include the AD8691 (single channel) and AD8694 (quad channel). Automotive qualified versions are available as AD8692W models. Verify pinout compatibility and thermal resistance differences if replacing with other packages in the series.
