ADA4051-2ACPZ-R7

Overview

The ADA4051-2ACPZ-R7 is a dual-channel, micropower, zero-drift operational amplifier manufactured by Analog Devices Inc. It utilizes an innovative chopping technique to achieve extremely low offset voltage and drift while maintaining rail-to-rail input and output swing. The device operates from a single supply ranging from 1.8 V to 5.5 V with a typical supply current of 13 μA per amplifier. Key electrical specifications include a maximum offset voltage of 15 μV, a gain-bandwidth product of 125 kHz, and high power supply rejection ratio (PSRR) and common-mode rejection ratio (CMRR). It is housed in an 8-lead LFCSP package.

Feature Summary

Utilizes an innovative chopping technique to suppress offset-related ripple without increasing in-band noise.
Features rail-to-rail input and output capability for maximum dynamic range operation.
Designed for unity-gain stability with extended industrial temperature range support.

Applications

Pressure and position sensors
Temperature measurements
Electronic scales
Medical instrumentation
Battery-powered equipment

Procurement Notes

Verify the specific ordering suffix R7 corresponds to the reel packaging configuration required for your assembly process. Confirm that the LFCSP-8 package dimensions align with your PCB footprint design. Ensure compatibility with the 1.8 V to 5.5 V supply voltage range intended for your system architecture before finalizing procurement.

Selection Notes

Select this component when designing circuits that require high precision combined with ultra-low power consumption. It is suitable for applications where battery life is critical but signal integrity must be maintained through low offset and drift characteristics. Consider the 125 kHz bandwidth limit when evaluating suitability for higher frequency signal processing tasks.

Part Context

This part belongs to the ADA4051 series of zero-drift amplifiers offered by Analog Devices. The -2 suffix indicates a dual-amplifier configuration within a single package, contrasting with the single-channel ADA4051-1. The ACPZ suffix denotes the specific 8-lead LFCSP package type, distinguishing it from other package options like MSOP available in the same family.
