With an 80 kHz -3 dB bandwidth, it is fast enough to capture switching ripple in a DC-DC converter or monitor load transients in a motor drive, but not intended for wideband servo loops or audio-frequency applications. The 12 µV input offset voltage means it can resolve small shunt voltages — down to microvolt-level signals — which translates to lower power dissipation in the shunt resistor for a given current. The 8-WLP (Wafer-Level Package) is a tiny, leadless package — essentially the bare die with solder bumps — that saves board area but demands a controlled assembly process. The mounting type is surface mount, and the package / case is 8-WFBGA, WLBGA, with the supplier device package listed as 8-WLP. Because it is a wafer-level package, the solder bumps are the only standoff; the board must have a solder mask defined pad pattern that matches the bump pitch exactly. Reflow profile follows standard lead-free (SnAgCu) recommendations, but the package is moisture-sensitive — MSL level should be verified from the latest datasheet revision before opening the sealed bag. ## Supply voltage and input offset — sizing the shunt and the rail The 12 µV input offset voltage is the key precision spec: it sets the floor on the smallest measurable shunt voltage. For a 10 mΩ shunt, 12 µV offset corresponds to a 1.2 mA error term — acceptable for multi-amp loads, but if you need to measure tens of milliamps, a larger shunt value or a lower-offset part would be needed. The input bias current is 65 µA, which flows into the shunt and can introduce a small additional error if the shunt resistance is high. For a 10 mΩ shunt, 65 µA × 10 mΩ = 0.65 µV, negligible against the 12 µV offset. The dual-channel configuration lets you monitor two independent current paths — for example, the input and output of a power supply, or two phases of a motor — with one IC.","metaTitle":"MAX44285TAWA+T Current Sense Amplifier, 80 kHz, 8-WLP","metaDescription":"MAX44285TAWA+T dual current-sense amplifier, 80 kHz bandwidth, 12 µV offset, -40°C to 125°C, 8-WLP package.
