Description

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.

The AD8598 has the same pinout as the DIP version of the AD9698. For a single comparator like the AD8598, please refer to the AD8561 data sheet.

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