CS3013
Low-power / Low-voltage Precision Amplifier
Features
& Description
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).
