The two channels let you monitor separate loads or differential currents from a single chip.
50 kHz bandwidth — fast enough for most switched loads
The -3 dB bandwidth of 50 kHz covers DC current sensing and slower PWM loops (motor drive at a few kHz, solenoid control). It won't capture fast edge transients in a high-frequency switching supply, but for average-current monitoring and overcurrent detection it's more than adequate. The 5 µV input offset keeps the error small even with a 10 mΩ shunt — you can read milliamps without a precision rail.
Package reality: 12-WLP means a hot-air station, not a soldering iron
This is a wafer-level package (1.7 x 1.27 mm) with no leads — the 12 bumps are on the bottom. That means no hand-soldering in the field; you need a reflow profile and a stencil. The upside is the footprint is tiny, so it fits on a cramped PCB next to the shunt resistor.
Active and available — no end-of-life worry
The ROHS3 compliance is current — no exemption expiry to track.
