The LT

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.
