It delivers a sensitivity of 200 mV/A, meaning every amp through the primary conductor produces 200 mV at the output pin, referenced to the supply. The 80 kHz bandwidth and 6.5 µs response time make it fast enough for switching power-supply loops and motor-phase monitoring, but not for sub-microsecond fault capture. The 8-SOIC package is a standard surface-mount footprint, easy to place on a production board or swap in the field with basic rework gear. ## Temperature range and environment Rated for -40°C to 125°C ambient, this sensor handles industrial enclosures, outdoor telecom cabinets, and under-hood automotive environments without a separate high-temp derivative. The ±0.5% linearity holds across that span, so you are not re-calibrating for seasonal temperature swings. ## Sourcing and lifecycle No end-of-life notice or last-time-buy schedule is in effect. There is no official second source listed, but the Hall-effect current-sensor market has several pin-compatible alternatives if dual-sourcing becomes a priority.","metaTitle":"TMCS1108A3UQDR Hall Effect Current Sensor, 200 mV/A, 8-SOIC","metaDescription":"TI TMCS1108A3UQDR Hall effect current sensor, 200 mV/A sensitivity, 80 kHz bandwidth, ratiometric voltage output, -40 to 125°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Output":"Ratiometric, Voltage","Package":"Tape & Reel (TR); Cut Tape (CT)","Frequency":"80kHz","Linearity":"±0.5%","Sensitivity":"200mV/A","Sensor Type":"Hall Effect","Polarization":"Unidirectional","For Measuring":"AC/DC","Mounting Type":"Surface Mount","Response Time":"6.5µs","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Current - Supply (Max)":"6mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.94","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.94000","currency":"USD"},{"qty":5,"price":"$2.73000","currency":"USD"},{"qty":10,"price":"$2.26800","currency":"USD"},{"qty":25,"price":"$1.89000","currency":"USD"},{"qty":50,"price":"$1.68000","currency":"USD"},{"qty":100,"price":"$1.59600","currency":"USD"},{"qty":500,"price":"$1.34400","currency":"USD"},{"qty":1000,"price":"$1.26000","currency":"USD"},{"qty":2500,"price":"$1.26000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ab54f153c251e13cd974bf31f09b5186.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the sensitivity of the TMCS1108A3UQDR?","answer":"The sensitivity is 200 mV/A.
