The LP339 is a quad comparator with ultra-low power consumption, single-supply operation, ground-sensing, and is compatible with the CMOS logic family.
The LP339 quad comparator is designed for single‑supply operation, drawing only about 60 µA across a wide voltage range. It features a common‑mode range that includes ground and output levels compatible with CMOS logic, making it suitable for battery‑powered and low‑power applications.
The device offers low input bias (3 nA) and offset currents (±0.5 nA), a typical input offset voltage of ±2 mV, and a high output sink current of up to 30 mA. It is supplied in both molded dual‑in‑line (LP339M) and standard dual‑in‑line (LP339N) packages.
| Input Offset Voltage | ±2 mV |
|---|---|
| Input Bias Current | 3 nA |
| Input Offset Current | ±0.5 nA |
| Output Sink Current | 30 mA (Darlington mode) |
| Operating Temperature Range | 0 °C to +70 °C |
| Input Common‑Mode Voltage Range | 0 V to V+‑1.5 V |
It can sink up to 30 mA when the output voltage is around 2 VDC (Darlington mode).
The typical input offset voltage is ±2 mV at 25 °C.
The device can tolerate up to 36 V DC or ±18 V DC on split supplies.
