LT119A/LT319A LM119/LM319 Dual Comparator
FEATURES DESCRIPTION
n Guaranteed Maximum 0.5mV Input Offset Voltage The LT®119A is an improved version of the LM119 dual n Input Protection Diodes comparator. It features lower input offset voltage and n Operates From Single 5V Supply offset current, higher voltage gain, guaranteed common n 25mA Drive Capability mode rejection and input protection diodes. n 80ns Response Time The LT119A is capable of operation over a supply range from 5V to ±15V and can drive 25mA loads from each
APPLICATIONS
open collector output. A separate ground pin allows the LT119A to isolate system grounds. n Window Detectors n Linear Technology Corporation’s advanced processing, High Speed One Shot n design techniques and reliability make the LT119A/LT319A Relay/Lamp Drivers n an ideal choice over previous devices in most comparator Voltage Controlled Oscillators applications.
