LT119A/LT319A

LM119/LM319

Dual Comparator

FEATURES

DESCRIPTION

■

Guaranteed Maximum 0.5mV Input Offset Voltage

Input Protection Diodes

Operates From Single 5V Supply

25mA Drive Capability

80ns Response Time

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
