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.
