LM393DR2G in LM339 / LM393 Comparators Family
The LM393DR2G belongs to the ubiquitous LM339/LM393 family of dual independent precision voltage comparators, manufactured by onsemi and other major semiconductor firms. Designed to operate from a single power supply over a wide range of voltages (2V to 36V), these devices are essential for basic signal processing. They feature open-collector outputs, allowing for logic level shifting and wired-OR connections, making them a staple in cost-sensitive analog-to-digital interface designs.
Variants in This Sub-Family
Variants within the LM393 sub-family primarily differ by temperature rating, packaging, and manufacturer-specific performance enhancements. The 'DR2G' suffix specifically denotes an SOIC-8 package on tape-and-reel. While the standard LM393 targets commercial temperatures (0°C to 70°C), the LM2903 variant extends this to industrial or automotive ranges (-40°C to +125°C). Additionally, pin-compatible CMOS versions offer lower power consumption but smaller voltage ranges.
