Overview
The LM339APT is a low-power quad voltage comparator produced by STMicroelectronics. This device is part of a family of comparators that include the LM139, LM239, and LM339. Each comparator in the LM339APT is designed to operate from a single power supply over a wide range of voltages, from 2 V to 36 V, or from dual supplies ranging from ±1 V to ±18 V. The device is known for its high precision, with an input offset voltage as low as 2 mV maximum for the LM339A, LM239A, and LM139A versions.
The LM339APT is packaged in a TSSOP-14 format and is RoHS compliant, making it suitable for a variety of industrial applications. It features very low supply current, low input bias and offset currents, and low output saturation voltage, making it highly efficient and reliable.
