It monitors current by sensing the voltage across a shunt resistor on the high side, with a supply span from 4.5 V up to 76 V. ## Package and mounting The 8-SOIC (0.154\", 3.90 mm width) surface-mount package is a standard footprint shared across many current-sense amplifiers. The supplier device package is also 8-SOIC.","metaTitle":"MAX4081FASA+ Current Sense Amplifier, 150 kHz, 8-SOIC","metaDescription":"MAX4081FASA+ current sense amplifier from Analog Devices. 4.5V to 76V supply, 150 kHz bandwidth, 103 µA supply current. -40°C to 125°C.

The closest pin-compatible alternative within the family shares the same supply range and bandwidth but differs in the internal gain setting — verify the gain resistor configuration in your design before substituting."},{"question":"Can MAX4081FASA+ be used for low-side current sensing?","answer":"This part is designed as a high-side current sense amplifier. The input common-mode range extends down to ground, but the output is referenced to the supply — for true low-side sensing with a ground-referenced output, a different topology is typically preferred. Confirm the common-mode range against your shunt voltage before using it in a low-side configuration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX4081FASA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX4081FASA when reusing this data.
