LMP2022 Overview
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.
