The 1mA maximum quiescent current keeps the thermal budget low even in densely populated modules. The 0.25µA input bias current at 5V minimises voltage drop across high-impedance source resistors. Supplied in an 8-VSSOP package (3.00mm width, 0.118\" pitch), the LM2903QDGKRQ1 is a surface-mount device that fits standard 8-pin TSSOP/MSOP land patterns. The supplier device package is 8-VSSOP; the alternate case codes are 8-TSSOP and 8-MSOP.","metaTitle":"LM2903QDGKRQ1 Dual Differential Comparator, AEC-Q100","metaDescription":"TI LM2903QDGKRQ1 dual differential comparator, AEC-Q100 qualified, 2V to 30V supply, -40°C to 125°C, 8-VSSOP.","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, 8-MSOP (0.118\\\", 3.00mm 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)":"6mA @ 5V","Propagation Delay (Max)":"-","Supplier Device Package":"8-VSSOP","Current - Quiescent (Max)":"1mA","Current - Input Bias (Max)":"0.25µA @ 5V","Voltage - Input Offset (Max)":"7mV @ 5V","Voltage - Supply, Single/Dual (±)":"2V ~ 30V, ±1V ~ 15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/91447dfa8c0b9268e485530ba4a5b230.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2903QDGKRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is LM2903QDGKRQ1 AEC-Q100 qualified?","answer":"Yes, the LM2903QDGKRQ1 is part of the Automotive, AEC-Q100 series, making it qualified for automotive-grade applications including under-hood and engine-bay environments."},{"question":"Is LM2903QDGKRQ1 a direct replacement for the standard LM2903?","answer":"The LM2903QDGKRQ1 is the AEC-Q100 qualified variant of the standard LM2903.
