LMP2021MFE/NOPB

LMP2021MFE/NOPB Description

The LMP2021MFE/NOPB from Texas Instruments is a high-precision, zero-drift operational amplifier (op-amp) designed for applications requiring ultra-low offset voltage and minimal input bias current. Part of the LMP® series, this single-channel op-amp operates over a 2.2V to 5.5V supply range, making it suitable for both low-voltage and standard industrial systems. Its 5 MHz gain bandwidth product (GBW) and 2.6V/µs slew rate ensure fast signal processing, while the 0.4 µV input offset voltage and 25 pA input bias current deliver exceptional DC accuracy. Packaged in a SOT23-5 form factor with tape-and-reel (TR) mounting, it is optimized for space-constrained designs.
