The wide supply range from 2V to 36V (or ±1V to ±18V dual supplies) lets it interface directly with 3.3V, 5V, 12V, or 24V rails without a separate level shifter. The 125°C ceiling covers under-hood automotive and industrial oven-adjacent placements that a 85°C commercial-grade comparator cannot handle. The 2.5mA max quiescent current per device keeps the thermal budget manageable in a sealed enclosure. ## Output drive and input offset — fit for threshold detection The 7mV max input offset at 30V supply sets the comparator's switching threshold accuracy — adequate for over-voltage/under-voltage detection, zero-crossing detectors, and window comparators where sub-millivolt precision is not required. The 0.25µA max input bias current at 5V minimises voltage drop across high-impedance source resistors.","metaTitle":"LM2903DRG3 Dual Differential Comparator, -40°C to 125°C","metaDescription":"Texas Instruments LM2903DRG3 dual differential comparator. 2V to 36V supply, open-drain output, industrial temp range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Type":"Differential","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Hysteresis":"-","Output Type":"CMOS, MOS, Open-Drain, 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 @ 30V","Voltage - Supply, Single/Dual (±)":"2V ~ 36V, ±1V ~ 18V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a3cec31cf9504607e64368e1c76ab997.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2903DRG3/alternatives.json"},"ai":{"faq":[{"question":"Can LM2903DRG3 replace LM393 in a design?","answer":"The LM2903DRG3 is a functional equivalent to the LM393 in most applications — both are dual differential comparators with open-drain outputs and similar pinouts. For designs that already use the LM393 and need wider temperature margin, the LM2903DRG3 is a drop-in replacement.
