LP311 Datasheet (National Semiconductor) - LP311 Voltage Comparator

LP311, LP311 Voltage Comparator

The LP311 is a low power version of the industry-standard LM311 It takes advantage of stable high-value ion-implanted resistors to perform the same function as an LM311 with a 30 1 reduction in power drain but only a 6 1 slowdown of response time Thus the LP311 is well suited for batterypowered appl
