AD8617ACPZ-RL

Overview

The AD8617ACPZ-RL 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. Key electrical characteristics include a maximum offset voltage of 2.2 mV, a maximum input bias current of 1 pA, and a typical supply current of 38 μA per amplifier. The device offers a gain-bandwidth product of 400 kHz, a slew rate of 0.1 V/μs, and a voltage noise density of 22 nV/√Hz at 10 kHz. It is housed in an 8-lead LFCSP package.

Feature Summary

• Rail-to-rail input and output operation enables full signal swing in low-voltage single-supply systems.
• Micropower consumption with a typical supply current of 38 μA per amplifier across the operating temperature range.
• Low noise performance with a voltage noise density of 22 nV/√Hz and peak-to-peak noise of 2.3 μV in the 0.1 Hz to 10 Hz band.
• Extremely low input bias current of 1 pA maximum, suitable for high-impedance sensor interfaces.

Applications

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

Procurement Notes

Verify the specific package option CP-8-21 (8-Lead LFCSP) matches the design footprint. Confirm that the suffix -RL7 indicates reel packaging if required by assembly equipment. Ensure the component meets RoHS compliance standards as indicated by the Z suffix in the base part number. Cross-reference the ordering guide to validate availability and manufacturing origin details.

Selection Notes

Select this component when dual-channel precision amplification is required within strict power constraints. The rail-to-rail I/O capability makes it ideal for buffering CMOS ADCs and DACs in portable devices. Consider the 8-lead LFCSP package for compact board space requirements compared to MSOP or SOIC alternatives.

Part Context

This part belongs to the AD8613/AD8617/AD8619 family of micro-power, low-noise CMOS op amps. The AD8617 specifically denotes the dual-channel configuration, whereas AD8613 is single-channel and AD8619 is quad-channel. All variants share identical electrical specifications but differ in pin count and package options.

Replacement Considerations

Direct functional substitutes within the same family include AD8617ACPZ-R2 and AD8617ACPZ-R7, which offer identical electrical performance but may differ in reel quantity or tape-and-reel specifications. Automotive-grade equivalents are available as AD8617WARMZ and AD8617WARZ variants.
