Comparators onsemi LM339DG Overview
The LM339DG by onsemi is a crucial component in the Comparators category, designed to offer reliable and precise voltage level comparisons across multiple applications. This quad single comparator integrates four independent precision voltage comparators in a compact 14-SOIC package, making it highly efficient for designs where space and power management are critical. The LM339DG ensures robust performance with its ability to operate from a single power supply over a wide range of voltages, or from dual supplies for increased flexibility. Its low power consumption and wide voltage range make the LM339DG an ideal choice for B2B customers looking to purchase in bulk for high-performance industrial, automotive, and consumer electronics applications.
LM339DG Features
- Four independent comparators
- Wide single or dual supply voltage range from 2V to 36V
- Low supply current drain independent of supply voltage
- Low input bias current
- Input common-mode voltage range includes ground
- Low output saturation voltage
- Output compatible with TTL, MOS, and CMOS
LM339DG Applications
- Industrial systems: In industrial environments, the LM339DG is used for process control and monitoring, ensuring systems operate within safe thresholds.
