In high-impedance sensor circuits (e.g., thermistor bridges, current-shunt monitors), the low bias current keeps the voltage error at the comparator input below 1 mV for source resistances up to 4 kΩ, preserving threshold accuracy without a buffer amplifier. ## Quiescent current and output drive Maximum quiescent current is 2.5 mA per comparator, and each output can sink or source up to 20 mA typical. The low idle current makes the part viable for always-on modules in automotive body controllers and battery-powered sensor nodes where the comparator is continuously powered. Supplied in an 8-SOIC package (0.154\" width, 3.90 mm body) with a 1.27 mm pitch.","metaTitle":"LM2903QDRG4Q1 Differential Comparator, AEC-Q100, 8-SOIC","metaDescription":"Texas Instruments LM2903QDRG4Q1 dual differential comparator, AEC-Q100 qualified, -40°C to 125°C, 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-SOIC (0.154\\\", 3.90mm 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-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":"$0.6000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/91447dfa8c0b9268e485530ba4a5b230.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2903QDRG4Q1/alternatives.json"},"ai":{"faq":[{"question":"How can I order LM2903QDRG4Q1 or check stock?","answer":"The LM2903QDRG4Q1 is an active-production part.

The 'G4' suffix in the order code indicates TI's green/RoHS-compliant plating. No separate RoHS certificate is required for standard procurement."},{"question":"Does LM2903QDRG4Q1 require external hysteresis?","answer":"Yes, like all open-loop comparators, the LM2903QDRG4Q1 does not have built-in hysteresis. For clean switching in noisy environments (e.g., automotive 12V/24V rails with alternator ripple), add positive feedback resistors between the output and non-inverting input. Typical values for a 10 mV hysteresis band at 5V supply are 1 MΩ feedback and 10 kΩ to ground."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2903QDRG4Q1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM2903QDRG4Q1 when reusing this data.
