LM2903DR2G in LM339 / LM393 Comparators Family
The LM2903DR2G belongs to the ubiquitous LM339/LM393 family of dual independent precision voltage comparators. Manufactured primarily by onsemi and Texas Instruments, these devices are designed to operate from a single power supply over a wide range of voltages. Featuring an open-collector output, they are specifically engineered to interface directly with TTL and CMOS logic, making them a staple in industrial and automotive electronics for level detection and signal conditioning tasks.
Variants in This Sub-Family
Variants within this family differ primarily in package types, ranging from SOIC-8 to Micro8, and temperature certifications. For instance, the LM2903 provides a wider operating temperature range (-40°C to +125°C) compared to the standard LM393. Automotive variants, often carrying the NCV prefix, undergo additional AEC-Q100 qualification and rigorous testing to ensure compliance with specialized reliability standards for vehicle electronics.
