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 open collector output. A separate ground pin allows the APPLICATIONS LT119A to isolate system grounds. n Window Detectors Linear Technology Corporations advanced processing, n High Speed One Shot design techniques and reliability make the LT119A/LT319A n Relay/Lamp Drivers an ideal choice over previous devices in most comparator n Voltage Controlled Oscillators applications.
