ADCMP567BCP

Overview

The ADCMP567BCP is a dual ultrafast voltage comparator fabricated on Analog Devices' proprietary XFCB process. It features a propagation delay of 250 ps and overdrive dispersion under 35 ps. The device operates with supply voltages of +5.0 V (VCC), -5.2 V (VEE), and +3.3 V (VDD). It provides differential PECL compatible outputs capable of driving 50 Ω transmission lines. Input common-mode range spans from -2.0 V to +3.0 V, with an input differential range of ±5 V. The component includes latch enable inputs for track-and-hold or sample-and-hold modes.

Feature Summary

• Ultrafast response with 250 ps propagation delay and minimal dispersion across varying overdrive conditions.
• Differential PECL compatible outputs providing sufficient drive current for direct transmission line termination.
• Integrated latch control enabling tracking, track-and-hold, or sample-and-hold operational modes.
• Robust input protection handling high ESD levels and wide differential input voltage ranges.

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 against the manufacturer's ordering guide to confirm package type and temperature range. Ensure power supply requirements match the design, as the device requires dual supplies for analog and logic sections. Confirm RoHS compliance status if required by project specifications. Check for any recent revision changes that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when sub-nanosecond timing accuracy is critical. The low propagation delay dispersion makes it suitable for applications where input slew rate or amplitude varies significantly. Ensure the PCB layout supports high-speed PECL signaling with proper ground planes and termination resistors. Consider the thermal resistance of the LFCSP package if operating near maximum junction temperatures.

Part Context

This part belongs to the ADCMP567 family of ultrafast comparators. It is designed using Analog Devices' XFCB process technology to achieve high bandwidth and low noise performance. The device is housed in a 32-lead Lead Frame Chip Scale Package (LFCSP) with an exposed pad for thermal management and grounding.

Replacement Considerations

Check the manufacturer's ordering guide for alternative packages or temperature grades within the same model series. Verify compatibility with existing PECL logic families if replacing older comparator designs. Ensure latch functionality requirements are met by potential substitutes.
