Product details

What this zero-drift amp brings to the board

It delivers a 5 MHz gain-bandwidth product with a 0.4 µV input offset voltage — the kind of precision that matters when you are amplifying a thermocouple, a strain-gauge bridge, or a shunt voltage where the signal is in the microvolt range and drift over temperature would swamp the measurement. The 2.6 V/µs slew rate is modest; this is not a video-line driver or a fast ADC buffer.

Supply span runs from 2.2 V to 5.5 V. Quiescent current is 1.1 mA. Output can source or sink 50 mA. Input bias current is 25 pA.

Frequently asked questions

Can LMP2021MF/NOPB be used in high-side current sensing applications?

Yes, but with caveats. The zero-drift topology and 0.4 µV offset make it suitable for sensing small differential voltages across a shunt. However, the input common-mode range does not extend to the positive rail — it is a standard op-amp input stage, not a rail-to-rail input. For high-side sensing above 3.3 V or 5 V, a dedicated current-sense amplifier like the INA254A1 is a better fit.

What is the pinout and footprint of LMP2021MF/NOPB?

The package is SC-74A / SOT-753, which is the standard SOT-23-5 footprint. Pin 1 is output, pin 2 is inverting input, pin 3 is non-inverting input, pin 4 is V– (ground), pin 5 is V+.
