CS3013-FSZ Cirrus Logic

10/15/09 CS3013 Low-power / Low-voltage Precision Amplifier Features & Description Description The CS3013 single amplifier is designed for precision Low Offset: amplification of low-level signals. These amplifiers 10 V Typ. achieve excellent offset stability, high open loop gain, Low Drift: and low noise. The device also exhibits excellent CMRR 0.05 V/C Max. and PSRR. The common mode input range includes the Low Noise: supply rails. The amplifiers operate with any supply volt- 22 nV/Hz age from 2.7 V to 5 V (1.35 V to 2.50 V). Open-loop Voltage Gain: 135 dB Typ.
