With a 250 kHz bandwidth, this part captures fast load transients—useful for detecting short-duration current spikes in motor drives or power converters. The 75 µA supply current keeps the quiescent draw low enough for always-on monitoring in battery-backed systems. ## Package and board-fit details Housed in an 8-TSSOP / 8-MSOP (0.118-inch, 3.00 mm width) package, the MAX4080FAUA+ is supplied in tube format. The supplier device package is designated 8-uMAX/uSOP, a common footprint for Analog Devices current-sense amplifiers. Surface-mount assembly is standard; the narrow 3 mm body fits tight layouts. ## Accuracy and input characteristics Input offset voltage is 100 µV typical—this sets the floor on measurable shunt voltage. For a 10 mΩ shunt, 100 µV offset corresponds to a 10 mA reading error at zero load. The 5 µA input bias current flows through the shunt and adds a small offset that can be calibrated out in firmware. The single-circuit topology means one amplifier per package; multiple channels require multiple devices. The 250 kHz bandwidth is the -3 dB point—above that frequency, gain rolls off, so the part is suited for DC and low-frequency AC current monitoring rather than high-speed switching waveforms. ## Lifecycle and compliance status It is ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive. No official successor or pin-compatible alternative is recorded; the part is the current offering in its series.","metaTitle":"MAX4080FAUA+ Current Sense Amplifier, 250 kHz, 8-uMAX","metaDescription":"MAX4080FAUA+ from Analog Devices: 4.5-76V supply, 75µA supply current, 250 kHz bandwidth, -40 to 125°C.
