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.
