Description
The CS3004 dual amplifier is designed for precision am-
plification of low-level signals. These amplifiers achieve
excellent offset stability, high open loop gain, and low
noise. The devices also exhibit excellent CMRR and
PSRR. The common mode input range includes the sup-
ply rails. The amplifiers operate with any supply voltage
from 2.7 V to 5 V (±1.35 V to ±2.50 V).
