DESCRIPTION
The LT
®
119A 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.
