AD8694ARZ-REEL

Overview

The AD8694ARZ-REEL is a quad, 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 specified over an extended industrial temperature range of −40°C to +125°C. The device features a gain bandwidth product of 10 MHz, a typical offset voltage of 400 µV, and a maximum input bias current of 1 pA. It delivers a slew rate of 5 V/µs and maintains unity-gain stability.

Feature Summary

• Quad configuration providing four independent amplifiers in a single package
• Rail-to-rail output capability for maximizing dynamic range
• Low noise performance suitable for precision signal conditioning
• 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 package type and reel specifications. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process. Confirm that the automotive qualification status aligns with project reliability standards before finalizing procurement.

Selection Notes

Select this component when multiple channels are required within a compact footprint. The quad architecture reduces board space compared to using individual single or dual amplifiers. Consider the 10 MHz bandwidth and low noise density for applications requiring high-speed signal processing with minimal distortion.

Part Context

This part belongs to the AD869x family of low-cost, low-noise CMOS operational amplifiers manufactured by Analog Devices Inc. The series includes single (AD8691), dual (AD8692), and quad (AD8694) variants sharing identical electrical characteristics. The ARZ designation indicates a commercial grade part housed in a standard narrow SOIC package.

Replacement Considerations

Direct substitutes include other parts from the AD869x family such as the AD8692 for dual-channel needs or the AD8691 for single-channel applications. Verify pin compatibility and package dimensions when replacing with non-family members.
