The thin profile helps when the PCB sits behind a display or in a tight enclosure. Surface-mount assembly with standard reflow profile; no underfill needed for the temperature range.","metaTitle":"LMP8640HVMKE-F/NOPB Current Sense, 450 kHz, TSOT-23-6","metaDescription":"Texas Instruments LMP8640HVMKE-F/NOPB current sense amplifier, 450 kHz GBW, 1.8 V/µs slew rate, -40 to 125°C.

The LMP8640HVMKE-F/NOPB offers a wider supply range (12 V vs 5.5 V) and a higher bandwidth (450 kHz vs 350 kHz), but the INA254A1IPWAR has a lower input bias current (0.1 µA vs 13 µA), which improves accuracy with low-value shunts.
