DESCRIPTION
The LT®1671 is a low power 60ns comparator with complementary outputs and latch. The input common mode range extends from 1.5V below the positive supply down to the negative supply rail. Like the LT1394, LT1016 and LT1116, this comparator has complementary outputs designed to interface directly to TTL or CMOS logic. The LT1671 may operate from either a single 5V supply or dual ±5V supplies. Low offset voltage specifications and high gain allow the LT1671 to be used in precision applications.
