LMP2021/LMP2022  
Zero Drift, Low Noise, EMI Hardened Amplifiers  
General Description  
Features  
The LMP2021/LMP2022 are single and dual precision oper-  
ational 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 at-  
tributes provide great precision in high accuracy applications.

The proprietary continuous correction circuitry guarantees  
impressive CMRR and PSRR, removes the 1/f noise compo-  
nent, and eliminates the need for calibration in many circuits.

Operating temperature range  
With only 260 nVPP (0.1 Hz to 10 Hz) of input voltage noise  
and no 1/f noise component, the LMP2021/LMP2022 are suit-  
able for low frequency applications such as industrial preci-  
sion 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 ap-  
plications. 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.
