ADCMP566BCPZ

Overview

The ADCMP566BCPZ is a dual ultrafast voltage comparator fabricated on Analog Devices’ proprietary XFCB process. It features a propagation delay of 250 ps with less than 35 ps overdrive dispersion. The device operates on dual supplies ranging from +4.75 V to +5.25 V and -4.96 V to -5.45 V, consuming typical supply currents of 13 mA and 70 mA respectively. It provides differential ECL compatible outputs capable of driving 50 Ω transmission lines terminated to -2.0 V. The input common-mode range spans from -2.0 V to +3.0 V, supporting an input differential range of ±5 V.

Feature Summary

• Ultrafast performance with 250 ps propagation delay and minimal overdrive dispersion for high timing accuracy.
• Differential latch control enabling tracking, track-and-hold, or sample-and-hold operational modes.
• Robust input protection handling differential voltages up to ±5 V and high ESD levels.
• Complementary digital outputs fully compatible with ECL 10 K and 10 KH logic families.

Applications

• High speed instrumentation
• Scope and logic analyzer front ends
• Window comparators
• High speed line receivers and signal restoration
• Threshold detection

Procurement Notes

Verify the specific suffix BC indicates the commercial temperature grade (-40°C to +85°C) and LFCSP-32 package configuration against the manufacturer's current ordering guide. Confirm that the required dual power supply rails (+5 V and -5.2 V) are available in the target design. Ensure proper ECL termination resistors are included in the schematic to match the specified output drive requirements.

Selection Notes

Select this component when sub-nanosecond propagation delay and low dispersion are critical for system timing integrity. The dual-channel architecture allows for independent processing of two signals within a single package. Consider the requirement for differential ECL outputs and the availability of negative supply rails before finalizing the design. Verify that the input signal slew rate meets the minimum requirement to prevent oscillation during threshold crossing.

Part Context
