Dual Comparator

FEATURES

DESCRIPTIO

■

Guaranteed Maximum 0.5mV Input Offset Voltage

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.
