LM393ADT in LM339 / LM393 Comparators Family
The LM393ADT series represents the industry-standard dual independent voltage comparator family manufactured by STMicroelectronics. Operating from a single or split power supply, these devices feature an open-collector output stage that allows for level shifting and wire-AND logic. They are characterized by a low supply current, wide input common-mode range reaching ground, and reliable performance across industrial temperature ranges, making them a staple for cost-effective analog signal monitoring in embedded systems.
Variants in This Sub-Family
Variants within the LM393/LM339 sub-family differ primarily by package type, temperature qualification, and channel count. The LM393ADT specifically denotes a dual comparator in an 8-pin Small Outline (SOIC) package. Other versions include the LM293 for extended temperature ranges, the LM193 for military specifications, and the LM339, which offers four identical comparator channels in a 14-pin footprint for higher density designs.
