Description
The CS3003 single amplifier is designed for precision
amplification of low-level signals. This amplifier achieves
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 amplifier operates with any supply voltage
from 2.7 V to 5 V (±1.35 V to ±2.50 V).
