Active precision op-amp with sub-microvolt offset
The LMP2011MF/NOPB is an active Texas Instruments precision op-amp in the LMP® series — no last-time-buy risk for new designs. Its 0.12 µV typical input offset voltage eliminates the need for external trimming or calibration in precision DC measurement paths, such as thermocouple amplifiers or current-sense front-ends.
Bandwidth, bias, and supply flexibility
With a 3 MHz gain-bandwidth product and 4 V/µs slew rate, the part handles moderate-speed signals up to a few hundred kHz at reasonable closed-loop gain — enough for sensor conditioning, data-acquisition buffers, or active filters in the audio band. Input bias current is 3 pA typical, which matters for high-impedance sources like pH probes or photodiode amplifiers where a nanoamp of bias would shift the DC operating point by millivolts across a 1 MΩ source resistance. Supply span runs from 2.7 V to 5.25 V, so it works on a single 3.3 V or 5 V rail without a negative supply. The rail-to-rail output swings to within a few millivolts of each rail, preserving dynamic range at low supply voltages.
Industrial temperature range and package fit
Rated for -40°C to 125°C ambient, the LMP2011MF/NOPB covers industrial control cabinets, engine-bay electronics, and outdoor instrumentation without a temperature grade upgrade. The SOT-23-5 package (SC-74A, SOT-753) fits tight PCB layouts but limits thermal dissipation — the 17 mA output current is sustainable into moderate loads, but driving a 50 Ω cable at full swing will raise the junction temperature above the ambient rating.
Sourcing and compliance
Texas Instruments lists the LMP2011MF/NOPB as Active with ROHS3 compliance. The part is quoted to order against BOM quantities through independent distribution; availability and current pricing are confirmed at RFQ time.
