LT1116CN8

模拟比较器 LT1116 - 12ns, Single Supply Ground-Sensing Comparator

DESCRIPTION

The LT® 1116 is an ultra fast 12ns comparator designed for sensing signals near the negative supply. The input common mode range extends from 2.5V below the positive supply down to the negative supply rail. Like the LT1016, this comparator is specifically designed to interface directly to TTL logic with complementary

outputs. The comparator may operate from either a single 5 V supply or dual ±5V supplies. Tight offset voltage specifications and high gain allow the LT1116 to be used in precision applications.
