Overview

The LMV339IPT is a low-voltage quad comparator featuring open-drain outputs, designed to operate from a single supply between 2.7V and 5.5V. This device provides a cost-effective solution for multi-channel signal monitoring in systems where low power consumption and space-saving 14-TSSOP packaging are required.

Why Choose This Part

This comparator offers a high integration density with four elements in a single 14-TSSOP package while maintaining a very low typical supply current of 20uA to 25uA per channel. Its rail-to-rail input capability and high output current capability of up to 93mA at 5V make it versatile for driving various loads or logic inputs.

Applications

Threshold Detection
Monitoring multiple sensor analog rails against a reference voltage for interrupt generation.
Logic Level Translation
Using the open-drain output and a pull-up resistor to interface between different logic voltage domains.
Window Comparators
Utilizing two or more channels to detect if a signal is within a specific voltage range.
Battery Monitoring
Detecting low-battery conditions in portable electronics due to its 20uA per channel typical quiescent current.
