Product details

What this part does — and where it fits

The MAX4072AUA+ is a single-channel current-sense amplifier with 100 kHz -3dB bandwidth and a supply span from 2.7 V to 24 V.

Supply current is 100 µA; input offset voltage is 80 µV. Input bias current is 2.4 µA.

Package and mounting — board-fit reality

The 8-uMAX/uSOP (3.00 mm × 3.00 mm body) is a common footprint shared with many Maxim current-sense amplifiers. Surface-mount only — no through-hole option. The 0.118" (3.00 mm) width keeps it on a tight PCB layout, but the small pad pitch demands careful solder-paste stencil design for reliable reflow.

Lifecycle and supply posture

Frequently asked questions

Is MAX4072AUA+ obsolete?

No — the MAX4072AUA+ has an Active lifecycle status. No EOL or NRND notice is in effect.

What is the equivalent of MAX4072AUA+?

The MAX4372 is a commonly cross-shopped current-sense amplifier in the same 8-uMAX package, but the MAX4072AUA+ has a 100 kHz bandwidth versus the MAX4372's 1.7 MHz — so they are not drop-in equivalents for designs that need the higher bandwidth. Verify the bandwidth requirement before substituting.

What package is MAX4072AUA+ in?

8-uMAX/uSOP (3.00 mm width, 0.118" body), surface-mount only. Supplied in Tube.
