Applications

Description

The CS3013 single amplifier is designed for precision

amplification of low-level signals. These amplifiers

achieve excellent offset stability, high open loop gain,

and low noise. The device also exhibits excellent CMRR

and PSRR. The common mode input range includes the

supply rails. The amplifiers operate with any supply volt-

age from 2.7 V to 5 V (±1.35 V to ±2.50 V).
