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 1.0 mA Supply Current Slew rate: –0.25 V/ µs Applications Thermocouple/Thermopile Amplifiers Load Cell and Bridge Transducer Amplifiers Precision Instrumentation Battery-powered Systems Description The CS3004 dual amplifier is designed for precision am- plification 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 sup- ply rails. The amplifiers operate with any supply voltage from 2.7 V to 5 V (±1.35 V to ±2.50 V).
