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.
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 into TTL logic or passive loads, yet it has minimal
cross-conduction current. Unlike other fast comparators,
the LT1116 remains stable even for slow transitions
through the active region, which eliminates the need to
specify a minimum input slew rate.
The LT1116 has an internal, TTL compatible latch for
retaining data at the outputs. The latch holds data as
long as the latch pin is held high. Device parameters
such as gain, offset, and negative power supply current
are not significantly affected by variations in negative
supply voltage.
