Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community LMP2021, LMP2022 SNOSAY9G – SEPTEMBER 2008 – REVISED FEBRUARY 2016 LMP202x Zero-Drift, Low-Noise, EMI-Hardened Amplifiers.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LMP2021 and 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 LMP202x has only 0.004 µV/°C of input offset voltage drift, and 0.4 µV of input offset voltage.
