Product details

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.

Frequently asked questions

What is the difference between MAX40080ANC+ and INA181?

The INA181 is a single-channel current-sense amp with a wider bandwidth (up to 350 kHz) and a larger package (SOT-23 or SC-70). The MAX40080ANC+ gives you two channels in a much smaller WLP footprint, but with a lower 50 kHz bandwidth. Choose the MAX40080 when you need dual channels and board space is the constraint; pick the INA181 for single-channel, higher-speed sensing in a more hand-solderable package.
