CS3003

CS3003 www.DataSheet4U.com Precision Low-voltage Amplifier Features & Description      Description The CS3003 single amplifier is designed for precision amplification of low-level signals. This amplifier achieves excellent offset stability, high open loop gain, and low noise. The devices also exhibit excellent CMRR and PSRR. The common mode input range includes the supply rails. The amplifier operates with any supply voltage from 2.7 V to 5 V (±1.35 V to ±2.50 V). Low Offset: – 10 μV Max. Low Drift: – 0.05 μV/°C Max. Low Noise: – 17 nV/√Hz Open-loop Voltage Gain: – 150 dB Typ.
