Description

The LT1671CMS8#PBF belongs to the product category of linear comparators. It is a low-power 60 ns comparator with complementary outputs and latch. The LT1671 can operate from either a single 5V supply or dual ±5V supplies. This comparator has complementary outputs designed to interface directly to TTL or CMOS logic. The input common mode range extends from 1.5V below the positive supply down to the negative supply rail. Low offset voltage specifications and high gain allow the LT1671 to be used in precision applications.
