The MAX4080FASA+ is a current-sense amplifier that operates from a 4.5 V to 76 V supply, with 250 kHz bandwidth and 75 µA supply current.
Bandwidth and input offset — measurement accuracy
The 250 kHz bandwidth captures current waveforms in switching converters. The 100 µV input offset and 5 µA input bias set the measurement floor.
The SOIC-8 footprint is widely used and easy to route; the device's pinout places the sense inputs on one side and the output and supply on the other, keeping the high-current sense traces away from the low-level output signal.
