CBMOPAZ201
Ultra-precision chopper-stabilized op-amp with 1μV offset and zero drift for high-precision DC measurements.
Product Overview
Description
The CBMOPAZ201 is an ultra-precision chopper-stabilized operational amplifier designed for high-precision DC measurement applications.
With 1μV maximum input offset voltage and zero drift over temperature, the CBMOPAZ201 delivers exceptional DC precision for bridge sensors, thermocouples, and other low-level signals.
The op-amp operates from single 2.2V to 5.5V supplies with rail-to-rail input and output.
