Product Information

LT119A/LT319A LM119/LM319 Dual Comparator FEATURES s s s s s DESCRIPTION The LT119A 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. The LT119A is capable of operation over a supply range from 5V to ±15V and can drive 25mA loads from each open collector output. A separate ground pin allows the LT119A to isolate system grounds. Linear Technology Corporation’s advanced processing, design techniques and reliability make the LT119A/LT319A an ideal choice over previous devices in most comparator applications.
