CS3004 Precision Dual Low-voltage Amplifier
Features & Description
Description
The CS3004 dual amplifier is designed for precision amplification of low-level signals. These amplifiers achieve 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 amplifiers operate 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.
Rail-to-Rail Inputs Rail-to-Rail Output Swing
– to within 10 mV of supply voltage
Pin Configurations
