LT119A/LT319A is an improved version of the LM119 dual comparator. It features lower input offset voltage and offset current, higher voltage gain, guaranteed common mode rejection, and input protection diodes. It is capable of operation over a supply range from 5V to ±15V and can drive 25mA loads from each open collector output.
The LT119A and LT319A are dual comparators from Linear Technology, offering low input offset voltage, high gain, and fast response. They operate from a single 5 V supply up to +15 V and can drive 25 mA loads per output.
The document provides absolute maximum ratings, electrical characteristics, typical performance curves, package dimensions, and example applications such as window detectors, high‑speed one‑shot circuits, and voltage‑controlled oscillators.
