LM339N in LM339 / LM393 Comparators Family
The LM339N family consists of quad independent precision voltage comparators designed to operate from a single power supply over a wide range of voltages. Manufactured by industry leaders like Texas Instruments, these components feature a unique common-mode input voltage range that includes ground, even when operated from a single supply. They are primarily utilized in industrial, automotive, and consumer electronics where multiple voltage levels must be monitored or compared with high reliability and low power consumption.
Variants in This Sub-Family
Comparing specs that differ across variants.
| Part Number | Temp Range | Current - Output (Typ) | Voltage - Input Offset (Max) | Voltage - Supply, Single/Dual (+/-) | Stock |
|---|---|---|---|---|---|
| LM339N (Texas Instruments) | 0degC ~ 70degC | 20mA | 5mV | 2V | 31,301 |
| LM339N/NOPB (Texas Instruments) | -25degC ~ 85degC | 16mA | 5mV | 2V | 18,468 |
Variants within the LM339N sub-family primarily differ in their packaging and environmental certifications. While the standard LM339N utilizes a 14-pin PDIP through-hole package for prototyping and legacy boards, the LM339N/NOPB designation signifies a lead-free, RoHS-compliant version required for modern manufacturing. Performance characteristics remain consistent across these versions, though specialized automotive-grade variants like the LM2901 offer extended temperature ranges for harsher operating environments.
