For a 100 kHz buck converter, the current sense output will settle within a switching cycle, giving the controller or ADC a clean signal. If your system needs to monitor sub-microsecond current spikes, this bandwidth may alias them — but for average current monitoring and overcurrent detection on most industrial and automotive rails, it is well matched. The 4.5 V minimum supply lets the part operate from a standard 5 V bias rail, while the 76 V maximum covers 48 V telecom buses with margin for transients. A single BOM line covers 12 V automotive, 24 V industrial, and 48 V PoE designs without respinning the current-sense block. The input offset voltage of 100 µV translates to a few milliamps of error on a typical 10 mΩ shunt — acceptable for most overcurrent thresholds.","metaTitle":"MAX4080SAUA-T Current Sense Amplifier, 250 kHz, 4.5-76 V","metaDescription":"MAX4080SAUA-T single current sense amplifier, 250 kHz bandwidth, 75 µA supply, 4.5 V to 76 V range, -40°C to 125°C, 8-µMAX package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Bulk","Mounting Type":"Surface Mount","-3db Bandwidth":"250 kHz","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"75µA","Number of Circuits":"1","Current - Input Bias":"5 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"100 µV","Supplier Device Package":"8-µMAX","Voltage - Supply Span (Max)":"76 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.42","stockQuantity":0,"priceTiers":[{"qty":211,"price":"$1.42000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9a338f76db050a41eb0b4026ac7c5cd4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the typical application for MAX4080SAUA-T?","answer":"It is a high-side current sense amplifier for monitoring supply rails from 4.5 V to 76 V.
