LM2901D in LM339 / LM393 Comparators Family
The LM2901D family consists of quad differential comparators designed to operate from a single power supply over a wide range of voltages. Produced by major manufacturers like Texas Instruments and STMicroelectronics, these devices feature four independent voltage comparators with an open-collector output configuration. They are industry-standard components for signal level detection and wave shaping, offering a cost-effective solution for multi-channel monitoring in industrial and automotive environments where robustness and supply flexibility are prioritized over high-speed switching.
Variants in This Sub-Family
Variants within the LM2901D sub-family primarily differ by package type and environmental screening. The standard LM2901D is typically supplied in a SOIC-14 package, while variants like the LM2901PWR offer smaller TSSOP footprints for space-constrained designs. Some versions include 'NOPB' suffixes indicating lead-free finishes, and others may carry automotive 'Q1' qualifications which involve more rigorous testing and AEC-Q100 compliance for use in vehicular control units.
