illustrate

The LMP2021/LMP2022 is an ultra-low input offset voltage with near-zero input offset voltage, offset voltage drift, very low input voltage noise, and very high open-loop gain op-amps with single precision and dual inputs. They are part of the LMP high-precision family and are the ideal instrument and sensor interface.

The LMP2021/LMP2022 has only a 0.004μV/°C offset voltage drift input and a 0.4μV input offset voltage. These properties provide high precision for applications that are very accurate.

The proprietary continuous correction circuitry guarantees impressive CMRR and PSRR, eliminating the 1/f noise component and eliminating the need for many circuit calibrations.

With only 260 NV PP (0.1 Hz to 10 Hz) of input voltage noise and a 1/f noise component, LMP2021/LMP2022 is ideal for applications such as industrial precision low-frequency scales. The low input bias of 23 pA current makes high sources such as non-invasive medical instruments and test and measurement equipment impedance circuits an excellent choice. The extremely high 160 dB open-loop gain greatly reduces gain and high gain application errors. With ultra-precise DC specifications and very low noise, LMP2021/LMP2022 is ideal for high-precision applications such as position sensors, bridge sensors, pressure sensors, medical devices, and very low error budgets.

LMP2021 is available in 5-pin SOT-23 and 8-pin SOIC packages. LMP2022 is available in 8-pin MSOP and 8-pin SOIC packages.
