Precision zero-drift amplifier for DC-accurate signal chains
The Analog Devices ADA4528-1ACPZ-R7 is a single-channel zero-drift operational amplifier that delivers a 0.3 µV typical input offset voltage and a 4 MHz gain bandwidth product. It operates from a 2.2 V to 5.5 V supply span, draws 1.5 mA quiescent current, and drives rail-to-rail outputs.
The 0.3 µV input offset voltage is the defining spec. For a thermocouple or strain-gauge amplifier, that offset translates directly to a DC error at the output.
