LMP2021/LMP2022 Zero Drift, Low Noise, EMI Hardened Amplifiers www.DataSheet4U.com July 23, 2009 LMP2021/LMP2022 Zero Drift, Low Noise, EMI Hardened Amplifiers General Description The LMP2021/LMP2022 are single and dual precision operational amplifiers offering ultra low input offset voltage, near zero input offset voltage drift, very low input voltage noise and very high open loop gain. They are part of the LMP® precision family and are ideal for instrumentation and sensor interfaces. The LMP2021/LMP2022 have only 0.004 µV/°C of input offset voltage drift, and 0.4 µV of input offset voltage. These attributes provide great precision in high accuracy 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 for low frequency applications such as industrial precision weigh scales. The low input bias current of 23 pA makes these excellent choices for high source impedance circuits such as non-invasive medical instrumentation as well as test and measurement equipment. The extremely high open loop gain of 160 dB drastically reduces gain error in high gain applications. With ultra precision DC specifications and very low noise, the LMP2021/LMP2022 are ideal for position sensors, bridge sensors, pressure sensors, medical equipment...
