CS3012中文资料凌云逻辑数据手册PDF规格书

描述 Description

The CS3011 single amplifier and the CS3012 dual amplifier are designed for precision amplification of lowlevel 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).
