LM2903PT in LM339 / LM393 Comparators Family
The LM2903PT family, primarily manufactured by STMicroelectronics and Texas Instruments, consists of dual independent precision voltage comparators designed to operate from a single power supply over a wide range of voltages. These devices are widely utilized for their low current consumption and ability to interface directly with TTL and CMOS logic. They provide an open-collector output, making them essential for level shifting, window comparison, and threshold detection in cost-sensitive industrial and consumer electronic designs.
Variants in This Sub-Family
Variants within this sub-family primarily differ based on their automotive qualification (AEC-Q100), temperature grades ranging from -40C to +125C, and physical packaging options such as TSSOP-8, SO-8, or MiniSO-8. Some specific versions offer tightened input offset voltage specifications (Vio) to improve accuracy in precision threshold sensing, while others are optimized for different output drive capabilities or ESD protection levels.
