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
and other high accuracy applications with very low error budgets.
The LMP2021 is offered in 5-Pin SOT-23 and 8-Pin SOIC packages. The LMP2022 is offered in 8-Pin MSOP and 8-Pin SOIC packages.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
