CS3001-ISZ

精密放大器 Low-Noise Op Amp Single 2.1mA

Description

The CS3001 single amplifier and the CS3002 dual amplifier are designed for precision amplification of low level signals and are ideally suited to applications that require very high closed-loop gains. These amplifiers achieve excellent offset stability, super-high open-loop gain, and low noise over time and temperature. The devices also exhibit excellent CMRR and PSRR. The common mode input range includes the negative supply rail. The amplifiers operate with any total supply voltage from 2.7 V to 6.7 V ±1.35 V to ±3.35 V.
