AD8692ARZ-REEL

Overview

The AD8692ARZ-REEL is a dual precision CMOS operational amplifier featuring rail-to-rail output and single-supply operation from 2.7 V to 6 V. It offers a gain bandwidth product of 10 MHz, a slew rate of 5 V/µs, and a typical offset voltage of 400 µV with a maximum drift of 6 µV/°C. Input bias current is typically 1 pA, while voltage noise density is 8 nV/√Hz at 1 kHz. The device operates over an extended industrial temperature range of −40°C to +125°C and is housed in an 8-lead narrow SOIC package.

Feature Summary

• Rail-to-rail output capability for maximizing dynamic range in low-voltage applications
• Low input offset voltage and drift ensuring high DC accuracy
• Very low input bias currents suitable for high impedance sensor interfaces
• Unity-gain stable design simplifying circuit implementation

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the reel packaging configuration. Ensure the component meets RoHS compliance requirements as indicated by the 'Z' suffix. Confirm that the automotive qualification status matches the project specifications, noting that standard commercial models differ from qualified automotive grades.

Selection Notes

Select this component when a dual-channel amplifier with rail-to-rail output is required within a 2.7 V to 6 V supply range. It is appropriate for applications demanding low noise and high speed, such as portable audio or precision filtering. Consider the 8-lead narrow SOIC package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the AD869x family of low-cost, low-noise CMOS operational amplifiers manufactured by Analog Devices Inc. The family includes single (AD8691), dual (AD8692), and quad (AD8694) variants sharing identical electrical characteristics. The AD8692 specifically provides two independent amplifiers in a compact surface-mount package.

Replacement Considerations

The AD8692ARMZ-R7 serves as a direct functional replacement utilizing an 8-lead MSOP package instead of the narrow SOIC form factor.
