The MAX4372HEUK+T comes in a SOT-23-5 package (SC-74A, SOT-753 case outline), surface-mount for compact PCB integration. The five-pin footprint occupies minimal board area, making it suitable for dense current-sense nodes on power rails or battery-monitoring circuits.
Key parametric and selection criteria
This is a single-circuit current sense amplifier with a 110 kHz -3 dB bandwidth, sufficient for monitoring DC rail currents and low-frequency load transients. The 30 µA supply current keeps the quiescent overhead low in always-on sense paths. The 300 µV input offset and 2 µA input bias are typical for this class; the offset dominates error at low shunt voltages, so choose a shunt resistor that keeps the sense voltage well above the offset floor.
ROHS3 compliant, which covers the current EU substance restrictions.
