The OP177 is an ultraprecision operational amplifier that offers ultralow offset voltage and excellent open-loop gain. It fits industry standard precision op amp sockets (OP07/OP77). The product provides high precision performance with an offset voltage of only 10µV and temperature drift (TCVOS) of 0.1µV/°C, increasing system accuracy over temperature. It also features excellent CMRR, PSRR, and low supply current.
This document provides a datasheet for the Analog Devices OP177, an ultralow offset voltage operational amplifier designed for high precision applications. Key features include an ultralow input offset voltage of 10 pV maximum at room temperature and 20 pV maximum over the full military temperature range, along with an outstanding offset voltage drift of 0.1 pV/°C maximum.
The datasheet details electrical characteristics for various sub-models (OP177A through OP177G) across military and industrial temperature ranges. It includes absolute maximum ratings, ordering guides for different package types (DIP, SO, LCC), and typical performance characteristics graphs regarding output voltage, supply voltage, and temperature.
