Its 450 kHz gain-bandwidth product and 1.8 V/µs slew rate suit it for DC-DC converter output monitoring, motor-phase current feedback, and power-rail supervision in industrial and automotive environments. The part operates across a 2.7 V to 12 V supply span and is rated over the full -40°C to 125°C temperature range, so it stays specified in engine-bay or factory-floor conditions. ## What the key ratings mean for the BOM The 450 kHz gain-bandwidth product sets the usable signal bandwidth. The 1.8 V/µs slew rate limits tracking of fast current transients. The part is offered in a SOT-23-6 Thin package with surface-mount termination. The supplier device package is SOT-23-THIN. No last-time-buy or end-of-life notice is in effect.","metaTitle":"TI LMP8640MKE-F/NOPB Current Sense Amplifier, 450 kHz GBW","metaDescription":"Texas Instruments LMP8640MKE-F/NOPB current sense amplifier in SOT-23-THIN. 450 kHz GBW, 1.8 V/µs slew rate, 2.7 V to 12 V supply.
