The two channels let you monitor independent rails — say a 5 V logic rail and a 12 V motor supply — with a single IC, saving board space over two single-channel parts. Rated for a supply span of 3 V to 28 V, the MAX4377FEUA runs directly off a 5 V or 12 V rail without an extra LDO. If your design sees sustained ambient above 85 °C, this part keeps working where a commercial-grade amp would drift or fail. ## Bandwidth and slew rate — fast enough for switching-load transients A 2 MHz -3 dB bandwidth and 10 V/µs slew rate let the amplifier track fast current changes from switching converters and motor drives. For a typical 500 kHz buck converter, the loop can resolve the inductor current ripple without significant phase lag. The 1 mA per-channel supply current keeps the quiescent draw low enough for always-on monitoring in battery-backed systems.","metaTitle":"MAX4377FEUA Current Sense Amplifier, Dual, 2 MHz, 10V/µs","metaDescription":"MAX4377FEUA dual current-sense amplifier from Maxim Integrated. 2 MHz bandwidth, 10V/µs slew rate, 3-28V supply, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Bulk","Slew Rate":"10V/µs","Mounting Type":"Surface Mount","-3db Bandwidth":"2 MHz","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1mA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"120 µA","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"8-µMAX","Voltage - Supply Span (Max)":"28 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.07","stockQuantity":0,"priceTiers":[{"qty":281,"price":"$1.07000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/aa4e86f5160707c20dbd84fa4c0d22ff.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX4377FEUA compatible with a 5 V supply?","answer":"Yes. The supply voltage range is 3 V to 28 V, so a 5 V rail is well within the operating window. No external regulator is needed."},{"question":"Does MAX4377FEUA have a shutdown pin?","answer":"The evidence does not list a shutdown pin. The device draws 1 mA per channel continuously when powered. If you need a low-power standby mode, consider adding a series FET or a load switch on the supply rail."},{"question":"What is the equivalent of MAX4377FEUA?","answer":"Within the same function class, the MAX4377 family includes single-channel variants (MAX4376) and other gain options. For a pin-compatible dual-channel current-sense amp, the MAX4378 is a sibling with a different gain set. Verify the gain and bandwidth match your shunt and load range before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX4377FEUA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX4377FEUA when reusing this data.
