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). □ Low Offset: -10 uV Max. □ Low Drift: -0.05 uV/°C Max. □ Low Noise: - 17 nV/VHz □ Open-loop Voltage Gain: - 150 dB Typ. □ Rail-to-Rail Inputs □ Rail-to-Rail Output Swing - to within 10 mV of supply voltage □ 2.1 mA Supply Current □ Slew rate: -0.25 V/us Applications □ Thermocouple/Thermopile Amplifiers □ Load Cell and Bridge Transducer Amplifiers □ Precision Instrumentation □ Battery-powered Systems Pin Configuration CS3004 (Top View) Out AE1 -In AD +In A [3 G V+ 7 Out B 5J +In B 8-Lead SOIC 1000 - - - — ■ - = = ■ - = = = = = — — - — — — — m m M m m M M m i = = = — - E - = EE E = = = = E EE -T 200 150 100 50 1 0 -50 -100 -150 -200 100 10 1 0.01 0.1 1 Frequency (Hz) 10 01 23456789 10 Time (sec) Noise vs. Frequency (Measured) 0.01 Hz to 10 Hz Noise Performance Cirrus Logic, Inc. http://www.cirrus.com Copyright © Cirrus Logic, Inc. 2009 (All Rights Reserved) JUL '09 DS719F2
