3 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. 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 circuits.
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.
