AD8629TRZ-EP-R7

Overview

The AD8629TRZ-EP-R7 is a dual-channel, zero-drift operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with an ultralow offset voltage of 1 µV typical and drift of 0.002 µV/°C typical. The device operates on a single supply from 2.7 V to 5 V or dual supplies of ±1.35 V to ±2.5 V. Key electrical parameters include a gain-bandwidth product of 2.5 MHz at 5 V, a slew rate of 1 V/µs, and a maximum input bias current of 100 pA. It provides high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of up to 140 dB and 130 dB respectively. The component is housed in an 8-lead SOIC package and supports extended industrial temperature ranges.
