Product details

Current sense amplifier for precision monitoring

The Texas Instruments LMP8640MKE-F/NOPB is a single-channel current sense amplifier in a SOT-23-THIN package, designed to measure load current by amplifying the voltage drop across a shunt resistor. 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.

Frequently asked questions

What is the gain bandwidth product of LMP8640MKE-F/NOPB?

The gain bandwidth product is 450 kHz. This defines the usable bandwidth for current sensing applications.

Is LMP8640MKE-F/NOPB a direct replacement for LMP8640MK?

The evidence does not list a direct replacement relationship. The LMP8640MKE-F/NOPB is the current active variant with ROHS3 compliance. Verify pin compatibility and electrical ratings against the specific LMP8640MK datasheet before substituting.
