LT1116 12ns, Single Supply Ground-Sensing Comparator
FeaTures DescripTion
n Ultra Fast (12ns Typ) The LT®1116 is an ultra fast (12ns) comparator designed n Operates off
Single
5V Supply or ±5V for sensing signals near the negative supply. The input n Input Common Mode Extends to Negative Supply common mode range extends from 2.5V below the n No Minimum Input Slew Rate Requirement posi tive supply down to the negative supply rail. Like n Complementary TTL Output the LT1016, this comparator is specifically designed to n Inputs Can Exceed the Positive Supply Up to 15V inter face directly to TTL logic with complementary without Damaging the Comparator outputs. The comparator may operate from either a single n Low Offset Voltage 5V supply or dual ±5V supplies. Tight offset voltage n Pin-Compatible with LT1016 specifi cations and high gain allow the LT1116 to be used n in precision applications. Output Latch Capability Available in 8-Lead PDIP and SO Packages The LT1116 is designed for improved speed and stability for a wide range of operating conditions. The output stage

provides active drive in both directions for maximum speed n into TTL logic or passive loads, yet it has minimal cross- High Speed A/D Converters conduction current. Unlike other fast comparators, the n Zero Crossing Detectors LT1116 remains stable even for slow transitions through n Current Sense for Switching Regulators the active region, which eliminates the need to specify a n Extended Range V to F Converters minimum input slew rate. n Fast Pulse Height/Width Discriminators n High Speed Triggers The LT1116 has an internal, TTL compatible latch for n Line Receivers retaining data at the outputs. The latch holds data as n long as the latch pin is held high.
