LP339DR Description

Short technical summary and product information.

The Texas Instruments LP339DR is a low-power, quad differential comparator IC housed in a 14-SOIC package. It operates over a wide supply voltage range from 3V to 30V and consumes a typical supply current of only 60µA. This comparator is designed for general-purpose applications and features low input bias and offset currents, as well as low input offset voltage.

 

The device offers high output sink-current capability and is compatible with MOS and CMOS logic. Its output types include CMOS, MOS, and Open-Collector. The operating temperature range is from 0°C to 70°C, and it is surface-mountable.

 

Applications for the LP339DR include limit comparators, simple analog-to-digital converters, pulse generators, squarewave generators, and voltage-controlled oscillators. Its pin-for-pin compatibility with LM239, LM339, and LM2901 makes it an easy drop-in replacement in many designs. The ultralow power consumption makes it ideal for battery-powered applications.
