The output stage supports CMOS, MOS, open-drain, and TTL logic families, so it interfaces directly with microcontrollers, PLDs, or discrete logic without level-shifting resistors. Two comparators in the 8-SOIC package (0.154\" width, 3.90mm body) save board area compared to two single-channel comparators. ## Industrial temperature grade and input characteristics Maximum input offset voltage is 7mV at 30V supply, and maximum input bias current is 0.25µA at 5V — adequate for threshold detection and zero-crossing circuits in noisy environments. Output current capability is 20mA typical, enough to drive a logic input or an LED indicator directly.","metaTitle":"LM2903DG4 Dual Differential Comparator, 2V-36V","metaDescription":"LM2903DG4 dual differential comparator from Texas Instruments. 2V to 36V supply, open-drain/CMOS/TTL outputs, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Type":"Differential","Series":"-","Package":"Tube","Hysteresis":"-","Output Type":"CMOS, MOS, Open-Drain, TTL","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","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":"$33.2400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a3cec31cf9504607e64368e1c76ab997.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2903DG4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM2903DG4?","answer":"Texas Instruments has not published an official successor for the LM2903DG4.
