AD8611 8-Lead, Ultrafast 4 ns Single Supply Comparator

The AD8611/AD8612 are single and dual 4 ns comparators with latch function and complementary output. The latch is not functional if VCC is less than 4.3 V. Fast 4 ns propagation delay makes the AD8611/AD8612 good choices for timing circuits and line receivers. Propagation delays for rising and falling signals are closely matched and tracked over temperature. This matched delay makes the AD8611/AD8612 good choices for clock recovery because the duty cycle of the output matches 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 are specified over the industrial temper-ature range (−40°C to +85°C). The AD8611 is available in both 8-lead MSOP and narrow 8-lead SOIC surface-mount packages. The AD8612 is available in a 14-lead TSSOP surface-mount package.
