The ADCMP566 is a dual ultrafast voltage comparator with a typical output rise/fall time of 165 ps, an input common-mode range of -2.0 V to +3.0 V, and an input differential range of ±5 V.
The ADCMP566 is a dual ultrafast voltage comparator fabricated on Analog Devices' proprietary XFCB process. It offers a typical propagation delay of 250 ps, differential ECL‑compatible outputs, and a latch enable function for track‑and‑hold operation. The device is supplied in a 32‑lead LFCSP package and is suited for high‑speed instrumentation, line receivers, and trigger applications.
Key features include a wide input common‑mode range (‑2.0 V to +3.0 V), robust ESD protection (>3 kV HBM), and high‑speed performance such as a 5 Gbps toggle rate and 200 ps minimum pulse width. Detailed electrical characteristics, pin descriptions, and timing diagrams are provided for design integration.
| Propagation delay (typical) | 250 ps |
|---|---|
| Input common‑mode range | ‑2.0 V to +3.0 V |
| Output rise time (20‑80 %) | 170 ps |
| Toggle rate (50 % swing) | 5 Gbps |
The typical propagation delay is 250 ps.
It supports an input common‑mode range from –2.0 V to +3.0 V.
The device can toggle at rates up to 5 Gbps for a 50 % output swing.
