It operates from a single supply between 2.7 V and 5.5 V. ## Temperature range and environment Rated for -40°C to 125°C operating temperature, so this part belongs in industrial motor drives, outdoor telecom rectifiers, and under-hood automotive modules – not just benign indoor gear. The 20 µA input bias current and 5 µV input offset voltage are typical for a precision current-sense amplifier; the offset contributes negligible error across the temperature span. ## Output drive and supply current The rail-to-rail output can source or sink 20 mA per channel – enough to drive an ADC input directly or feed a low-impedance control loop. Supply draw is 6 mA, which matters if you are powering the amp from a tight bias rail on a multi-channel board. ## Lifecycle and sourcing posture The MAX40056FAUA+ carries an active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX40056FAUA+ Current Sense Amplifier, 300 kHz, Rail-to-Rail","metaDescription":"MAX40056FAUA+ current sense amplifier from Analog Devices. 300 kHz bandwidth, rail-to-rail output, 2.7 V to 5.5 V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Slew Rate":"1.5V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"300 kHz","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"6mA","Number of Circuits":"1","Current - Input Bias":"20 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"5 µV","Supplier Device Package":"8-uMAX/uSOP","Current - Output / Channel":"20 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.69","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.69000","currency":"USD"},{"qty":10,"price":"$3.31700","currency":"USD"},{"qty":25,"price":"$3.13600","currency":"USD"},{"qty":100,"price":"$2.71790","currency":"USD"},{"qty":250,"price":"$2.57852","currency":"USD"},{"qty":500,"price":"$2.31370","currency":"USD"},{"qty":1000,"price":"$1.95132","currency":"USD"},{"qty":2500,"price":"$1.85375","currency":"USD"},{"qty":5000,"price":"$1.78406","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX40056F-MAX40056U.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can the MAX40056FAUA+ be used for high-side or low-side current sensing?","answer":"Yes, as a current-sense amplifier it works on either the high side or low side of the supply rail.
