Overview
The LMV339IPWRE4 is a quad low-voltage comparator from Texas Instruments, part of the LMV339 series. These devices are low-voltage versions of the industry-standard LM339 comparators, designed to operate from 2.7 V to 5.5 V. This makes them highly suitable for applications where low power consumption, low voltage operation, and space-saving design are critical. The LMV339 is particularly useful in portable consumer products and other general-purpose low-voltage applications.
