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 voltage from 2.7 V to 5 V (±1.35 V to ±2.50 V).
Low Offset:
– 10 μV Typ.
Low Drift:
– 0.05 μV/°C Max.
Low Noise:
– 22 nV/√Hz
Open-loop Voltage Gain:
– 135 dB Typ.
Rail-to-Rail Inputs Rail-to-Rail Output Swing
– to within 20 mV of supply voltage
