DESCRIPTION

Dual Comparator

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.
