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. The -40°C to 125°C operating temperature range qualifies it for under-hood automotive, outdoor telecom enclosures, and factory-floor sensor interfaces — not just benign indoor gear.
Supply current and input offset — what they mean for the BOM
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
The MAX4072AUA+ has an Active lifecycle status and is ROHS3 compliant.
