Current sense amp in a SOT-23-5 — what you get
The MAX4376HAUK: It's built for the classic high-side current-monitoring job: sense a voltage across a shunt resistor and output a ground-referenced voltage proportional to the load current. The -3 dB bandwidth is 2 MHz and the slew rate is 10 V/µs, which means it can catch fast current transients — useful in motor-drive fault detection or power-supply short-circuit events. Quiescent current is 1 mA, which keeps the thermal budget modest.
Package and mounting
The 10 V/µs slew rate and 3 V minimum supply span are specified in the datasheet. The 120 µA input bias current is typical for a current-sense amplifier.
