The AD8561 is a single 7 ns comparator with separate input and output sections. Separate supplies enable the input stage to be operated from ±5 V dual supplies and +5 V single supplies. Fast 7 ns 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 configuration as the AD8562 and AD8563 and comes in the same packages.
The AD8561 comparator offers a 7 ns propagation delay at a 5 V supply, single‑supply operation from 3 V to 10 V, and low power consumption (typical 5 mA). It features a latch function, optional hysteresis, and is pin‑compatible with the LT1016.
The datasheet provides detailed electrical specifications, absolute maximum ratings, ordering information for multiple package types, typical performance curves, and application notes for high‑speed timing, clock recovery, and line‑receiver designs.
