LM2901DR in LM339 / LM393 Comparators Family
The LM2901DR family, produced by Texas Instruments and other major semiconductor manufacturers, consists of quad independent precision voltage comparators. These devices are designed specifically to operate from a single power supply over a wide range of voltages, though split-supply operation is also possible. Known for their versatility and low power consumption, they are essential components in signal conditioning and monitoring circuits within industrial and automotive environments where open-collector outputs are required for logic interfacing.
Variants in This Sub-Family
Variants within this sub-family primarily differ based on temperature grade, package type, and precision ratings. While the standard LM2901 is rated for automotive and industrial temperatures, specific suffixes like 'Q' denote AEC-Q100 qualification. Differences also exist in input offset voltage specifications and ESD protection levels between manufacturers, though pinout and functional characteristics remain consistent across the DR (SOIC) and PWR (TSSOP) package variants.
