The AD8598 is a dual 7 ns comparator with digital latches. Separate supplies enable the input stage to be operated from +5 V to as high as ±5 V.

Ultrafast 7 ns propagation delay makes the AD8598 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 AD8598 a good choice for clock recovery, since the duty cycle of the output will match the duty cycle of the input.

For a single comparator like the AD8598, please refer to the AD8561 data sheet.

The AD8598 is specified over the industrial (-40°C to +85°C) temperature range. The AD8598 is available in both the 16-lead plastic DIP, 16-lead TSSOP or narrow R-16A surface mount packages.
