AD8661ACPZ-REEL7

Overview

The AD8661ACPZ-REEL7 is a precision single operational amplifier manufactured by Analog Devices Inc. It utilizes CMOS technology and features a rail-to-rail output capability, allowing operation with supply voltages up to 16V. The device offers a gain-bandwidth product of 4 MHz and a slew rate of 3.5 V/us. Key electrical specifications include a maximum input offset voltage of 1200 uV and a maximum supply current of 1.2 mA. It is housed in an 8-lead SOIC package.

Feature Summary

• CMOS architecture designed for low power consumption while maintaining high precision performance characteristics.
• Rail-to-rail output stage enables full signal swing across the entire supply voltage range.
• Single-channel configuration provides a compact solution for space-constrained circuit designs.

Applications

• Precision signal conditioning circuits requiring low noise and high accuracy
• Battery-powered instrumentation systems due to low quiescent current
• Active filtering applications within audio and sensor interfaces

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when ordering. Confirm the AC sub-series designation matches the required offset voltage and bandwidth specifications for the target application. Ensure the SOIC-8 footprint aligns with the PCB layout constraints before finalizing procurement.

Selection Notes

Select this component for applications demanding a balance between precision and power efficiency. The CMOS process allows for lower power dissipation compared to bipolar counterparts. Verify that the 4 MHz bandwidth meets the signal frequency requirements and that the rail-to-rail output satisfies the dynamic range needs of the downstream circuitry.

Part Context

This part belongs to the AD866x family of precision amplifiers from Analog Devices. The family includes dual (AD8662) and quad (AD8664) variants sharing similar electrical characteristics. The AD8661 specifically addresses single-channel requirements, offering a cost-effective alternative to multi-channel packages when only one amplifier is needed.

Replacement Considerations

Direct functional substitutes within the same family include the AD8662ARZ-REEL7 and AD8664ARZ-REEL7, provided pin compatibility and channel count requirements are adjusted accordingly. Cross-family replacements require careful verification of pinout and electrical parameter alignment.
