LM2901N in LM339 / LM393 Comparators Family
The LM2901N family, primarily manufactured by Texas Instruments and ON Semiconductor, consists of industry-standard quad differential comparators designed to operate from a single power supply over a wide range of voltages. These devices are specifically engineered to provide low power consumption and a high common-mode input voltage range that includes ground. They are fundamental building blocks in analog signal processing, offering open-collector outputs that simplify interfacing with various logic levels in industrial and automotive systems.
Variants in This Sub-Family
Comparing specs that differ across variants.
| Part Number | Temp Range | Current - Output (Typ) | Voltage - Supply, Single/Dual (+/-) | Stock |
|---|---|---|---|---|
| LM2901N/NOPB (Texas Instruments) | -40degC ~ 85degC | 16mA | 2V | 2,985 |
| LM2901N (Texas Instruments) | -40degC ~ 125degC | 20mA | 2V | 3,613 |
Variants within the LM2901N sub-family primarily differ by packaging and environmental ratings. The standard LM2901N typically denotes the PDIP package, favored for through-hole prototyping and legacy maintenance. The NOPB suffix indicates a lead-free transition under the National Semiconductor lineage now owned by TI. While the internal silicon remains largely consistent, automotive-grade versions (Q1) offer enhanced temperature range testing and AEC-Q100 qualification for harsher operating environments.
