The 2V minimum supply lets the comparator run from a single lithium cell or a 3.3V rail, while the 36V maximum covers 24V industrial buses and 12V/24V automotive systems without an external regulator.","metaTitle":"LM2903QDG4 Dual Differential Comparator, 2V-36V, -40°C-125°C","metaDescription":"TI LM2903QDG4 dual differential comparator, 2V to 36V supply, -40°C to 125°C, open-drain/CMOS/TTL outputs.","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":"$5.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0a4d96519aaa123766ebea6dd789822b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2903QDG4/alternatives.json"},"ai":{"faq":[{"question":"Is LM2903QDG4 obsolete?","answer":"Yes, the LM2903QDG4 is listed as obsolete by Texas Instruments.
