description

™The LT 1671 is a low-power complementary output and latched 60ns comparison. The input common mode range drops from a positive supply voltage of 1.5V to below the negative rail. Like the LT1394, LT1016 and LT1116, this has complementary output direct interface TTL or CMOS logic. The LT1671 can be operated from a single 5V supply or dual ± 5V supply. The low offset voltage specification and high gain allow the LT1671 to be used in high-precision applications. LT1671 is designed for increased speed and stable operating conditions in a wide range. TTL, CMOS or passive load output stages provide active drivers in both directions with minimal cross-conduction current and maximum speed. Unlike other fast comparators, the LT1671 remains stable even through active regions, eliminating the need to specify a minimum input conversion speed for slow conversion. The LT1671 has an internal TTL/CMOS compatible latch output for data retention. The latch holds the latch pin as long as the data is held high. Device parameters such as gain, offset, and negative supply current are not significantly affected by changes in negative supply voltage.
