| Parameter | LM2904DR | LM2904DR | Engineering note |
|---|---|---|---|
| Package and exact order code | TI LM2904DR: SOIC D package, 8 pins, 2500-unit large tape and reel | UMW LM2904DR: SOP-8, 2500-unit tape and reel | Both exact order codes use the standard 8-pin dual-op-amp pinout and a 1.27 mm nominal lead pitch. TI calls the package SOIC while UMW calls it SOP; PCB land pattern, paste aperture, assembly tolerances and thermal design still require independent release checks. |
| Input offset voltage | 7 mV maximum at 25 C; 10 mV maximum over -40 C to +125 C | 7 mV maximum at 25 C; 10 mV maximum over -40 C to +125 C | The reviewed room-temperature and full-range offset maxima correspond for the non-A LM2904. |
| Recommended supply and temperature range | 3 V to 26 V; -40 C to +125 C for LM2904 | 3 V to 26 V; -40 C to +125 C | The exact-code recommended voltage span and ambient range correspond. Do not apply LM2904V or enhanced-B-version limits to this order code. |
| ESD and thermal data | TI specifies HBM and CDM ESD ratings and package thermal metrics | An equivalent ESD and thermal-resistance set was not found in the reviewed UMW datasheet | Do not copy TI's ESD, junction-temperature or thermal-resistance limits to the target. Board-level ESD and thermal margin require independent evaluation. |
FAE documentary review accepted for the exact TI LM2904DR and UMW LM2904DR order codes. Both are standard 8-pin dual operational amplifiers with 7 mV maximum room-temperature input offset, 10 mV maximum full-range input offset, a 3 V to 26 V recommended supply and a -40 C to +125 C ambient range. Both exact codes use a 1.27 mm nominal lead pitch and 2500-unit tape and reel. The reviewed target document does not provide an equivalent complete ESD and thermal data set, and package naming differs as SOIC versus SOP. Document review only; not bench, temperature-cycle, EMC, reliability or production qualified.
Cross-reference suggestions for LM2904DR are provided for engineering convenience and are based on published specifications, vendor documents, or parametric analysis as labeled on each entry. They do not constitute an endorsement by, or an affiliation with, STMicroelectronics, and they are not a guarantee of suitability for any specific application. Always validate alternatives against both manufacturers' current datasheets and your own qualification process before production use.
