Overview
The LP339MX/NOPB is an ultra-low power quad comparator produced by Texas Instruments. This component consists of four independent voltage comparators designed to operate from a single power supply, drawing a typical power supply drain current of 60 µA. It is capable of functioning over a wide range of power supply voltages (2 V to 36 V) and can also operate from split supplies. The LP339MX/NOPB features a common-mode range that includes ground, even when operated from a single supply, making it highly versatile for various applications.
