GENERAL DESCRIPTION
The AD8611/AD8612 are single and dual 4 ns comparators with
latch function and complementary output.
Fast 4 ns propagation delay makes the AD8611/AD8612 a good
choice for timing circuits and line receivers. Propagation delays
for rising and falling signals are closely matched and track over
temperature. This matched delay makes the AD8611/AD8612 a
good choice for clock recovery, since the duty cycle of the output
will match the duty cycle of the input.
The AD8611 has the same pinout as the LT1016 and LT1394,
with lower supply current and a wider common-mode input range,
which includes the negative supply rail.
The AD8611/AD8612 is specified over the industrial (–40°C to
+85°C) temperature range. The AD8611 is available in both 8-lead
MSOP and narrow SO-8 surface mount packages. The AD8612
is available in 14-lead TSSOP surface-mount package.
