LM2903ST in LM339 / LM393 Comparators Family
The LM2903ST is a member of the industry-standard LM2903 sub-family, manufactured primarily by STMicroelectronics. It is a dual independent voltage comparator designed specifically for operation from a single power supply over a wide range of voltages. This family is recognized for its low current drain, which remains independent of the magnitude of the power supply voltage, making it a staple for power-sensitive monitoring and threshold detection in industrial and automotive electronics.
Variants in This Sub-Family
Variants within the LM2903ST sub-family primarily differ by temperature grade, packaging, and specific qualification standards. While the standard LM2903 covers industrial ranges, the LM2903W variants offer enhanced ESD protection. Packaging options like MiniSO8 (MSOP8), TSSOP8, and SO8 dictate thermal dissipation limits and footprint compatibility, whereas 'A' versions often denote tighter offset voltage specifications for more precise signal discrimination in sensitive analog front-ends.
