ADCMP567BCPZ

Overview

The ADCMP567BCPZ is a dual ultrafast voltage comparator fabricated on Analog Devices' proprietary XFCB process. It features a 250 ps propagation delay and less than 35 ps overdrive dispersion. The device operates with a common-mode input range from −2.0 V to +3.0 V and provides differential PECL compatible outputs capable of driving 50 Ω transmission lines directly. It includes differential latch control for track-and-hold or sample-and-hold modes, robust ESD protection exceeding 3 kV HBM, and operates within a temperature range of −40°C to +85°C in a 32-lead LFCSP package.

Feature Summary

• Ultrafast performance with 250 ps propagation delay and minimal overdrive dispersion for high timing accuracy.
• Differential PECL compatible outputs designed to drive 50 Ω transmission lines directly without additional buffering.
• Integrated differential latch enable inputs supporting tracking, track-and-hold, and sample-and-hold operational modes.
• Robust input protection mechanisms including high ESD tolerance and wide differential input voltage range.

Applications

• High speed instrumentation
• Scope and logic analyzer front ends
• Window comparators
• High speed line receivers and signal restoration
• Automatic test equipment

Procurement Notes

Verify the specific ordering suffix BC to confirm the commercial temperature grade (-40°C to +85°C) and RoHS compliance status as indicated in the manufacturer's ordering guide. Ensure power supply configurations match the required dual supply voltages (+5.0 V, -5.2 V, and +3.3 V) for optimal electrical characteristics. Confirm that the 32-lead LFCSP package dimensions align with the target PCB footprint requirements.

Selection Notes

Select this component when sub-nanosecond propagation delay and low dispersion are critical for system timing integrity. The differential PECL output interface is suitable for high-speed digital systems requiring direct transmission line driving capabilities. Consider the integrated latch functionality if sample-and-hold operations are needed within the comparison stage. Evaluate the thermal resistance of the LFCSP package against the expected power dissipation under load conditions.

Part Context

The ADCMP567 belongs to Analog Devices' family of ultrafast voltage comparators designed for precision timing applications. Utilizing the proprietary XFCB process, it offers superior speed compared to standard bipolar comparators. The dual-channel architecture allows for independent operation or paired usage in differential signaling applications, providing a compact solution for high-density circuit designs requiring fast signal threshold detection.

Replacement Considerations

Consult the official Analog Devices ordering guide for verified substitute part numbers within the same product family. Ensure any replacement maintains compatibility with the 32-lead LFCSP package and PECL output interface specifications.
