400 kHz bandwidth, 5 µV offset — current-sense amp for shunt monitoring
The INA240A1D: Its 400 kHz -3dB bandwidth supports monitoring of switching waveforms in DC-DC converters and motor drives, while the 5 µV input offset voltage keeps the zero-current error low enough for sub-milliohm shunts.
Quiescent supply current is 1.8 mA typical, which is low enough to keep the thermal contribution negligible in a densely populated 8-SOIC layout, but not the lowest in the INA240 family — the A1 variant trades a slightly higher bias for wider bandwidth.
