The MAX4376FAUK+T is a single-circuit current sense amplifier in a SOT-23-5 package (SC-74A, SOT-753). Tape & Reel (TR) and Cut Tape (CT) options are available; the TR variant is the standard reel for pick-and-place, while CT suits prototype or low-volume builds.
The 500 kHz -3 dB bandwidth and 10V/µs slew rate mean this amplifier can track fast current transients — useful for monitoring switching regulator output or motor phase currents where the signal changes faster than a general-purpose op-amp can follow. The supply voltage span of 3 V to 28 V covers common rails from 3.3 V logic to 24 V industrial buses, and the 1 mA supply current keeps the overhead low in a power-sensitive node. The single-circuit configuration (one amplifier per package) simplifies PCB layout for point-of-load current sensing — no unused channels to terminate.
