AD8694ARUZ

Overview

The AD8694ARUZ is a quad, low-cost, low-noise CMOS operational amplifier featuring rail-to-rail output and single-supply operation from 2.7 V to 6 V. It offers a typical offset voltage of 400 µV with a maximum drift of 6 µV/°C and very low input bias currents of 1 pA maximum. The device provides a wide bandwidth of 10 MHz and a slew rate of 5 V/µs. It operates within an extended industrial temperature range of −40°C to +125°C and is housed in a 14-lead TSSOP package.

Feature Summary

• Features low offset voltage and minimal drift for high precision applications
• Provides rail-to-rail output capability on a single supply
• Maintains stability with unity gain configurations
• Delivers wide signal bandwidth and low distortion

Applications

• Photodiode amplification

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Confirm that the automotive grade variants are selected only when specific reliability reports are required for automotive environments.

Selection Notes

Select this component for designs requiring low noise and high speed in a single-supply environment. Consider the 14-lead TSSOP package for space-constrained PCB layouts. Evaluate the low input bias current suitability for high-impedance sensor interfaces. Verify thermal characteristics against the expected operating temperature range.

Part Context

This part belongs to the AD8691/AD8692/AD8694 family of low-cost, low-noise CMOS operational amplifiers. The series includes single, dual, and quad configurations sharing similar electrical characteristics. These amplifiers are designed for applications benefiting from low offset, low noise, and wide bandwidth performance.

Replacement Considerations

Direct substitutes include other members of the AD869x family such as the AD8691 or AD8692, provided the channel count matches the design requirements. Verify pin compatibility and package dimensions before substitution.
