Product details

What a 200 kHz current-sense amp gives you in a SOT-23-5

The MAX4372FEUK+T is a single-channel current-sense amplifier from Analog Devices, packaged in a SOT-23-5 (SC-74A) footprint. Its 200 kHz bandwidth means it can track load transients and PWM ripple in the tens-of-kilohertz range without significant gain roll-off — useful for monitoring a motor-drive bus or a switching-regulator output where the ripple frequency sits below 100 kHz. Supply current is 30 µA typical, which keeps the quiescent draw low enough for always-on current monitoring in battery-powered gear or for a sense circuit that stays live while the rest of the board sleeps.

Input offset voltage is 300 µV typical; that sets the floor on how small a shunt voltage you can resolve before the offset dominates the error. Input bias current is 2 µA, which flows through the shunt and adds a small voltage drop — factor it in when choosing the shunt value for a low-side measurement.

Frequently asked questions

What is the MAX4372FEUK+T pinout?

The MAX4372FEUK+T comes in a 5-pin SOT-23-5 (SC-74A) package. The pin functions are standard for this family: supply, ground, input sense terminals, and output. The exact pin mapping is in the manufacturer's datasheet.

Can MAX4372FEUK+T be used for low-side current sensing?

Yes — it is a unidirectional current-sense amplifier that works for low-side sensing where the shunt sits between the load and ground. The input common-mode range includes ground, so the shunt voltage is referenced to the same ground as the amplifier's supply.

Is MAX4372FEUK+T RoHS compliant?

Yes, it is rated ROHS3 compliant.
