The AD8561ARUZ is an ultrafast single-supply Comparator with separate input and output sections. Separate supplies enable the input stage to be operated from ±5V dual supplies and 5V single supplies. Fast 7ns propagation delay makes the AD8561 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 AD8561 a good choice for clock recovery, since the duty cycle of the output will match the duty cycle of the input. The AD8561 has the same pin-out as the LT1016 with lower supply current and a wider common-mode input range, which includes the negative supply rail.
