LM339D 5mV 0.25uA 4 SOIC-14 Comparator SMD IC
The LM339D is a high-performance integrated circuit containing four independent voltage comparators. It is designed to operate from a single power supply over a wide voltage range and is ideal for low-power applications in industrial, automotive, and consumer electronics.
✅Features
- Quad Comparison: Four independent differential comparators in a single SOIC-14 package.
- Wide Supply Range: Operates on a single supply voltage from 2V to 30V.
- Ground-Sensing Input: Common-mode input voltage range includes ground, allowing direct sensing near 0V.
- High Differential Input: Differential input voltage range is equal to the maximum-rated supply voltage (±36V).
- Low Input Parameters: Features a low input offset voltage (5mV max) and low input bias current (250nA max).
- Logic Compatibility: Outputs are fully compatible with TTL, MOS, and CMOS logic systems.
- Low Power Consumption: Quiescent current is independent of the supply voltage magnitude.
