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
The LMP202x has 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 auto zero correction circuitry ensures impressive CMRR and
PSRR, removes the 1/f noise component, and eliminates the need for calibration in many
With only 260 nVPP (0.1 Hz to 10 Hz) of input voltage noise and
no 1/f noise component, the LMP202x are suitable for low frequency applications such as industrial
precision weigh scales. 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 LMP202x
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 VSSOP and 8-Pin SOIC packages.
