Description
The CS3001 single amplifier and the CS3002 dual am-
plifier 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 de-
vices 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).
