Description
The CS3011 single amplifier and the CS3012 dual am-
plifier 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 de-
vices 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).

Notes: 1. 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. Start-
up time applies to when supply voltage is applied or when PDWN is released.
