Package and exact order codeTI LM324ADR: SOIC D package, 14 pins, 2500-unit large tape and reelUMW LM324ADR: SOP-14, 2500-unit tape and reelBoth exact order codes use the standard 14-pin quad-op-amp pinout and a nominal 1.27 mm lead pitch. TI calls the package SOIC while UMW calls it SOP; the PCB land pattern, paste aperture, assembly tolerances and thermal design still require independent release checks.
Input offset voltage at 25 C3 mV maximum7 mV maximumThe target's specified offset window is wider. Precision DC-gain, threshold and low-level signal applications must budget for the extra 4 mV or select a tighter target grade.
Temperature range and characterization0 C to +70 C for the exact LM324ADR order code0 C to +70 C; electrical table tested up to a 30 V VCC maximumThe exact ambient range matches. UMW does not publish an equivalent full-temperature input-offset table in this reviewed datasheet, so full-range accuracy cannot be inferred from the room-temperature limit.
ESD and thermal dataTI specifies HBM and CDM ESD ratings and package thermal metricsAn equivalent ESD and thermal-resistance set was not found in the reviewed UMW datasheetDo 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 LM324ADR and UMW LM324ADR order codes. Both are 14-pin quad operational amplifiers with the standard pinout, 0 C to +70 C exact-code rating, 2500-unit tape and reel, and a 1.27 mm nominal lead pitch. The target's room-temperature input-offset maximum is 7 mV versus TI's 3 mV, and the reviewed target document does not provide an equivalent set of full-temperature offset, ESD or thermal limits. These are documentary comparisons; no bench, temperature-cycle, EMC, reliability or production qualification was performed.
