AD8659ACPZ-RL

Overview

The AD8659ACPZ-RL is a quad micropower, precision, rail-to-rail input/output CMOS operational amplifier from Analog Devices. It operates on a single supply of 2.7 V to 18 V or dual supplies of ±1.35 V to ±9 V with a maximum quiescent current of 22 μA per amplifier. Key electrical specifications include a maximum offset voltage of 350 μV, a maximum input bias current of 20 pA, and a gain bandwidth product of 230 kHz at AV = 100. The device features unity-gain stability, excellent electromagnetic interference immunity, and is specified over an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Quad-channel architecture providing four independent precision amplifiers in a single package.
• Rail-to-rail input and output capability for maximizing dynamic range across the full supply voltage.
• Micropower consumption optimized for battery-operated and energy-efficient applications.
• Patented DigiTrim technology ensures low offset voltage and high precision.

Applications

• Current monitoring in process and motor control systems
• Buffering and level shifting for sensor front ends
• Multipole filter circuits
• Remote and wireless sensor transmitters

Procurement Notes

Verify the specific ordering suffix ACPZ-RL against the manufacturer's latest documentation to confirm the LFCSP package type and reel packaging configuration. Ensure compatibility with the required thermal management and PCB footprint specifications for the 16-lead LFCSP form factor before integration.

Selection Notes

Select this component when a quad-channel configuration is required alongside low power consumption and high precision. The wide supply voltage range and rail-to-rail performance make it suitable for diverse signal conditioning tasks where space and power are constrained compared to dual-channel alternatives.

Part Context

The AD8659 serves as the quad-channel counterpart to the dual-channel AD8657 within the same precision micropower family. Both devices share identical electrical characteristics and core technologies but differ in channel count and physical package options, allowing designers to scale channel density without compromising performance specifications.

Replacement Considerations

The AD8657ACPZ-RL is a compatible dual-channel alternative if fewer channels are sufficient. Verify pinout compatibility and ensure the application does not require the additional two channels provided by the quad configuration.
