CS3011 CS3012 Precision Low Voltage Amplifier; DC to 1 kHz Features Low Offset: 10 µV Max Low Drift: 0.05 µV/°C Max Low Noise – 12 nV/√Hz @ 1.0 Hz – 0.1 to 10 Hz = 250 nVp-p – 1/f corner @ 0.08 Hz Description The CS3011 single amplifier and the CS3012 dual amplifier are designed for precision amplification of low level 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).

Symbol “•” denotes specification applies over -40 to +85 ° C. 2. This parameter is guaranteed by design and laboratory characterization. Thermocouple effects prohibit accurate measurement of these parameters in automatic test systems. 3. 1000-hour life test data @ 125 °C indicates randomly distributed variation approximately equal to measurement repeatability of 1 µV. 4. Measured within the specified common mode range limits. 5. Guaranteed within the output limits of (V+ -0.3 V) to (V- +0.3 V). Tested with proprietary production test method. 6. PWDN input has an internal pullup resistor to V+ of approximately 800 kΩ and is the major source of current consumption when PWDN is pulled low. 7. The device has a controlled start-up behavior due to its complex open loop gain characteristics. Startup time applies to when supply voltage is applied or when PDWN is released. 2 CS3011 CS3012 1.2 ABSOLUTE MAXIMUM RATINGS Parameter Supply Voltage Input Voltage Storage Temperature Range [(V+) - (V-)] V- -0.3 -65 Min Typ Max 6.8 V+ +0.3 +150 Unit V V ºC 2.
