LM339AMX/NOPB TI Comparator | 14-SOIC | Quad, Open Collector, 2V to 36V

Product Overview

The LM339AMX/NOPB is a quad differential comparator from Texas Instruments, designed for low-power, high-precision voltage comparison in industrial and automotive applications. Housed in a compact 14-SOIC package, it operates over a wide supply voltage range of 2V to 36V (or ±1V to ±18V) and features open-collector outputs for wired-AND configurations. With a typical response time of 1.3 µs, it is suitable for battery management, motor control, and signal conditioning.
