What are the key features of LMP2022MA?
- Zero-drift architecture keeps input offset voltage below 10 µV over temperature, eliminating periodic re-calibration in precision measurement systems
- 141 dB typical CMRR and 105 dB minimum CMRR suppress common-mode noise in differential sensing applications
- Ultra-low bias current of 0.3 nA max enables use with high-impedance sensors and electrochemical cells without loading error
What is LMP2022MA used for?
The LMP2022MA is designed for precision DC measurement applications including strain gauge bridge amplification, thermocouple signal conditioning, and current-shunt monitoring where offsets below 10 µV are essential. Its zero-drift topology keeps gain error stable over the full industrial temperature range, making it suitable for data acquisition front-ends in medical instrumentation and industrial weigh scales. The 8-pin SOIC package and single-supply compatibility allow straightforward integration into portable and rack-mounted measurement systems.

Frequently Asked Questions
How does the zero-drift architecture of the LMP2022MA maintain accuracy over temperature in a strain-gauge bridge circuit?
The zero-drift technique continuously corrects input offset voltage through an internal auto-zeroing or chopper-stabilized loop, keeping offset below 10 µV across the operating temperature range. In a 350 Ω strain-gauge bridge with 5 V excitation, this translates to a DC error contribution of less than 2 µV/V, enabling bridge measurements with sub-milligram resolution in precision weigh scale designs.
What makes the LMP2022MA suitable for high-impedance electrochemical sensor interfaces compared with a standard op-amp?
The LMP2022MA has a maximum input bias current of 0.1 µA at 25°C, dropping to an average of 0.3 nA, which is far lower than a standard bipolar op-amp's bias currents in the range of 1 µA to 10 µA. This prevents significant voltage error at the input when connected to high-impedance electrochemical electrodes whose source impedance can exceed 1 MΩ.
In which package does the LMP2022MA ship, and how does that affect soldering and thermal management on a compact PCB?
The LMP2022MA is housed in an 8-pin SOIC package with a standard 1.27 mm pitch, supporting wave, reflow, and manual soldering. The SOIC footprint occupies approximately 5 mm × 4 mm of board area and allows adequate thermal dissipation for typical low-power precision amplifier quiescent currents, making it suitable for dense 4-layer PCB designs in portable instruments.
