description

The TL3116 is an ultra-fast comparator designed

to interface directly to TTL logic while operating

from either a single 5-V power supply or dual

±5-V supplies. The input common-mode voltage

extends to the negative rail for ground sensing

applications. It features extremely tight offset

voltage and high gain for precision applications. It

has complementary outputs that can be latched

using the LATCH ENABLE terminal. Figure 1

shows

the

positive

supply

current

of

the

comparator. The TL3116 only requires 12.7 mA

(typical) to achieve a propagation delay of 10 ns.

The TL3116 is a pin-for-pin functional replace-

ment

for

the

LT1116

comparator,

offering

high-speed operation but consuming much less

power.
