AD8617WARZ-R7

Overview

The AD8617WARZ-R7 is a dual-channel, low-cost, micropower CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates from a single supply of 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.5 V. The device offers a maximum offset voltage of 2.2 mV, a maximum input bias current of 1 pA, and a typical voltage noise density of 25 nV/√Hz at 1 kHz. Supply current is limited to 50 μA per amplifier across the temperature range. It is unity gain stable, qualified for automotive applications, and housed in an 8-lead SOIC package.

Feature Summary

• Rail-to-rail input and output operation enables full signal swing in low-voltage single-supply systems.
• Micropower consumption with a maximum supply current of 50 μA per amplifier over the operating temperature range.
• Low input bias current of 1 pA maximum minimizes loading effects on high-impedance sources.
• Automotive qualification ensures reliability and controlled manufacturing standards for vehicle electronics.

Applications

• Battery-powered instrumentation
• Multipole filters
• Current shunt sense circuits
• ADC predrivers
• DAC drivers and level shifters

Procurement Notes

Verify that the component matches the specific automotive grade designation (W suffix) required for your application environment. Confirm the package type is the 8-lead SOIC variant as indicated by the model number. Ensure the reel packaging format aligns with your automated assembly equipment specifications before finalizing procurement orders.

Selection Notes

Select this component when designing portable or loop-powered instrumentation requiring low power consumption without sacrificing precision. The rail-to-rail I/O functionality makes it suitable for buffering CMOS ADCs and DACs in systems where maximizing dynamic range is critical under tight voltage constraints.

Part Context

This part belongs to the AD8613/AD8617/AD8619 family of low-cost, micropower, low-noise CMOS op amps. While the AD8613 is single-channel and the AD8619 is quad-channel, the AD8617 provides a dual-channel configuration. All variants share similar electrical characteristics but differ in channel count and available package options.

Replacement Considerations

The AD8617ARMZ serves as a commercial-grade alternative in the same 8-lead MSOP package. For automotive applications requiring the same dual-channel configuration but in an MSOP package, the AD8617WARMZ-REEL is a compatible substitute within the same family.
