简  介:CS3011 CS3012 Precision Low-voltage Amplifier; DC to 1 kHz Features & Description Offset: 10 μV Max Low Drift: 0.05 μV/°C Max Low Noise Low Description The CS3011 single amplifier and the CS3012 dual amplifier are designed for precision amplification of lowlevel signals and are ideally suited to applications that require very high closed-loop gains. These amplifiers achieve excellent offset stability, super-high open-loop gain, and low noise over time and temperature. The devices also exhibit excellent CMRR and PSRR. The common mode input range includes the negative supply rail. The amplifiers operate with any total supply voltage from 2.7 V to 6.7 V (±1.35 V to ±3.35 V). – 12 nV/√Hz @ 0.5 Hz – 0.1 to 10 Hz = 250 nVp-p – 1/f corner @ 0.08 Hz Open-loop Voltage Gain – 300 dB Typ – 200 dB Min Rail-to-rail Output Swing Slew Rate: 2 V/μs Pin Configurations CS3011 PDWN 1 -In +In V2 3 4 + 8 7 6 5 NC V+ Output NC Out A 1 -In A 2 +In A 3 V- 4 A - + + B CS3012 8 V+ 7 Out B 6 -In B 5 +In B Applications Thermocouple/Thermopile Amplifiers Load Cell and Bridge Transducer Amplifiers Precision Instrumentation Battery-powered Systems 8-lead SOIC 8-lead SOIC Noise vs. Frequency (Measured) 100 nV/√Hz CS3011 Dexter Research Thermopile ST60 10 R2 64.9k 1 0.001 0.010 0.1 Frequency (Hz) 1 10 R1 100 C1 0.015μF http://www.cirrus.com Copyright Cirrus Logic, Inc. 2009 (All Rights Reserved) JUL ‘09 DS597F6 CS3011 CS3012 TABLE OF CONTENTS 1.
