Overview
The LP339DRG4 is a low-power quadruple differential comparator produced by Texas Instruments. This device is part of the LP339 series, which is characterized for operation from 0°C to 70°C. The LP339DRG4 is designed to operate from a single power supply, with a wide supply-voltage range of 3 V to 30 V, making it versatile for various applications. It features ultra-low power-supply current, typically 60 µA, which is independent of the power-supply voltage, making it suitable for battery-powered devices.
