Each output is open-collector, allowing wired-OR connections and level translation to CMOS, MOS, or TTL logic families. The 2 V to 36 V single-supply range means this comparator can be powered directly from an automotive battery line or a regulated 3.3 V / 5 V rail without a secondary supply. The 2.5 mA maximum quiescent current per device keeps the standing power low in always-on modules like window lift controllers or seat-position sensors. The 0.25 µA maximum input bias current at 5 V minimises voltage error when the comparator is used with high-impedance sensor bridges or resistive dividers. Maximum input offset voltage is 7 mV at 5 V, which sets the threshold accuracy floor for window comparators and zero-crossing detectors. For applications requiring tighter offset, the standard LM2901 or an automotive-grade precision comparator would be needed. ## Package, mounting, and lifecycle The base product number is LM2901, and this variant carries the 'V' suffix indicating AEC-Q100 qualification and the 'Q1' suffix for automotive-grade release.","metaTitle":"TI LM2901VQDRQ1 Quad Differential Comparator, AEC-Q100","metaDescription":"TI LM2901VQDRQ1 quad differential comparator, AEC-Q100 qualified, -40°C to 125°C, 2V to 36V supply, open-collector outputs, 14-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Type":"Differential","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Hysteresis":"-","Output Type":"CMOS, MOS, Open-Collector, TTL","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"-","Number of Elements":"4","Base Product Number":"LM2901","Operating Temperature":"-40°C~125°C","Current - Output (Typ)":"20mA","Propagation Delay (Max)":"-","Supplier Device Package":"14-SOIC","Current - Quiescent (Max)":"2.5mA","Current - Input Bias (Max)":"0.25µA @ 5V","Voltage - Input Offset (Max)":"7mV @ 5V","Voltage - Supply, Single/Dual (±)":"2V ~ 36V, ±1V ~ 18V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2367","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f358abf583109cd938feed2069e7d3ae.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2901VQDRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is LM2901VQDRQ1 AEC-Q100 qualified and suitable for automotive?","answer":"Yes, the series is listed as Automotive, AEC-Q100.
