| 10/15/09 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 V Typ. Low Drift: - 0.05 V/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 Pin Configurations CS3013 (Top View) 0.5 mA Supply Current Slew rate: - 0.25 V/s NC 1 1 2 3 4 + 8 NC 7 6 5 V+ 1 Applications -IN +IN V- Thermocouple/Thermopile Amplifiers Load Cell and Bridge Transducer Amplifiers Precision Instrumentation Battery-powered Systems Output NC 1 1.
