Description
LMV393DR2G is TI’s dual low-voltage comparator in an 8-pin package. It’s used for simple threshold and level-sensing tasks in battery-powered systems.
Key features:
- Dual channels with rail-to-rail input and open-drain outputs (pull-ups required)
- Supply range: 2.7 V to 5.5 V
- Industrial temperature range: -40°C to +125°C
- Low quiescent current and fast response for a comparator family
Typical applications:
- Battery monitors, voltage detectors, level sensing, and microcontroller threshold detection
DR2G denotes the specific packaging variant (check TI’s datasheet for exact package type, RoHS, and tape/reel details).
Design notes:
- Use pull-ups on outputs
- Ensure input common-mode stays within the approved range relative to Vcc
- Choose pull-up values to meet speed and voltage requirements
For exact electrical specs and packaging, refer to the TI LMV393DR2G datasheet.
