LM339AN in LM339 / LM393 Comparators Family
The LM339AN is a quad differential voltage comparator family manufactured by Texas Instruments and other leading semiconductor vendors. Featuring four independent comparators designed to operate from a single power supply over a wide range of voltages, it is a staple in analog signal processing. The LM339AN utilizes an open-collector output configuration, allowing for easy level shifting and logical OR-ing of outputs, making it ideal for interfacing between different voltage domains in industrial and consumer electronics.
Variants in This Sub-Family
Variants within the LM339 sub-family primarily differ in their operating temperature ranges and packaging options. The 'N' suffix denotes a plastic dual-in-line (PDIP) package, while 'D' or 'PW' variants indicate SOIC or TSSOP surface-mount configurations. Additionally, the 'A' version, such as the LM339AN, features tighter specifications for input offset voltage compared to the standard LM339, providing better accuracy for sensitive threshold detection.
