LMP2021/LMP2022 Zero Drift, Low Noise, EMI Hardened Amplifiers www.DataSheet4U.com July 23, 2009 LMP2021/LMP2022 Zero Drift, Low Noise, EMI Harden.
The LMP2021/LMP2022 are single and dual precision operational amplifiers offering ultra low input offset voltage, near zero input offset voltage drift.
Features
* (Typical Values, TA = 25°C, VS = 5V)
* 0.4 µV
* Input offset voltage (typical) ±5 µV
* Input offset voltage (max) -0.004 µV/°C
* Input offset voltage drift (typical) ±0.02 µV/°C
* Input offset voltage drift (max) 11 nV/√Hz
* Input voltage noise, AV = 1000 160 dB
* Open
Applications
* The proprietary continuous correction circuitry guarantees impressive CMRR and PSRR, removes the 1/f noise component, and eliminates the need for calibration in many circuits. With only 260 nVPP (0.1 Hz to 10 Hz) of input voltage noise and no 1/f noise component, the LMP2021/LMP2022 are suitable fo
