LM339AM/NOPB TI Comparator | 14-SOIC | Quad, 2V to 36V, Low Power

Product Overview

The LM339AM/NOPB is a quad differential comparator from Texas Instruments, designed for general-purpose applications requiring low power consumption and wide supply voltage range. Housed in a 14-SOIC package, this device features four independent comparators that operate from a single power supply over a wide voltage range of 2V to 36V, or dual supplies of ±1V to ±18V. The LM339AM/NOPB is characterized by low input offset voltage, low input bias current, and open-collector outputs that allow wired-AND connections. It is ideal for battery-powered systems, industrial controls, and automotive electronics.
