High-side current sense in a 4x4 QFN
The MAX34406TETG+ is a high-side current sense IC from Analog Devices, designed to measure current flowing from the supply rail to the load rather than from the load to ground. This topology keeps the sense resistor in the supply path, which avoids ground-loop injection and lets the load reference a clean ground plane — a real advantage in mixed-signal boards where the analog and digital grounds share a return.
Package and rework reality
The part ships in a Tube, which means it arrives in an antistatic tube rather than tape-and-reel. For a prototype or low-volume build, this is convenient — no feeder setup, just hand-place or use a pick-and-place with a tube feeder. For high-volume reflow, you will want to order tape-and-reel packaging if available; the tube format is more common for engineering samples and small production runs.

Sourced through independent distribution channels. No stock-holding claim is made — each order is sourced to the BOM quantity.
