The part operates from 2.7 V to 12 V and is specified over the full -40°C to 125°C industrial range, making it suitable for under-hood automotive, factory-floor automation, and outdoor telecom equipment. Housed in a thin SOT-23-6 (SOT-23-THIN) package, it saves board space on dense analog front-ends. The 450 kHz GBP sets the usable closed-loop bandwidth. Input offset voltage is trimmed to 900 µV. ## Package and ordering variants The LMP8640MK-F/NOPB is supplied in a thin SOT-23-6 (SOT-23-THIN) package, surface-mount only. The ordering code suffix /NOPB indicates lead-free (RoHS3-compliant) construction.","metaTitle":"TI LMP8640MK-F/NOPB Current Sense Amplifier, 450 kHz, SOT-23","metaDescription":"TI LMP8640MK-F/NOPB current sense amplifier in SOT-23-THIN. 450 kHz GBP, 1.8 V/µs slew rate, -40 to 125°C.
