Input offset voltage is specced at 7mV max at 5V, which is the parametric limit the test engineer will check against the application threshold — tighter than the generic LM393 family. Housed in an 8-TSSOP package with 0.65mm pin pitch — the footprint fits a standard SOIC-8 land pattern with a slight pad width adjustment, so a layout engineer can reuse an existing dual-op-amp footprint with a minor stencil revision. Surface-mount only; the Tape & Reel option (TR suffix) is the production-friendly format for automated pick-and-place, while Cut Tape (CT) suits prototype runs. Base product number LM2903 has been in continuous production across multiple temperature and package variants — this V-grade (-40°C to 125°C) is the automotive-tier option and sees steady demand, not a niche short-run suffix.","metaTitle":"Texas Instruments LM2903VQPWRG4Q1 Dual Differential","metaDescription":"TI LM2903VQPWRG4Q1 dual differential comparator, AEC-Q100 qualified, -40°C to 125°C range, 2V to 36V supply.","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":"8-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"-","Number of Elements":"2","Base Product Number":"LM2903","Operating Temperature":"-40°C~125°C","Current - Output (Typ)":"20mA","Propagation Delay (Max)":"-","Supplier Device Package":"8-TSSOP","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":"$0.6000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/91447dfa8c0b9268e485530ba4a5b230.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2903VQPWRG4Q1/alternatives.json"},"ai":{"faq":[{"question":"Is LM2903VQPWRG4Q1 a direct drop-in replacement for LM2903DR?","answer":"The LM2903VQPWRG4Q1 differs from the standard LM2903DR in two ways that matter for a BOM swap: the V-grade extends the operating temperature range to 125°C (vs 85°C on the base part), and the Q1 suffix confirms AEC-Q100 qualification. The pinout and package (8-TSSOP) are the same, so it is a functional drop-in if the application needs the wider temperature range and the Q100 cert.
