Description
The CS3011 single amplifier and the CS3012 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).
