AD8468WBKSZ-R7

Overview

The AD8468WBKSZ-R7 is a single-channel, rail-to-rail analog comparator from Analog Devices. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and features TTL/CMOS-compatible outputs. The device includes a shutdown pin for power management and is qualified for automotive applications. It utilizes an XFCB2.0 process technology to achieve low propagation delay and low power consumption within a compact 6-lead SC-70 package.

Feature Summary

• Rail-to-rail input common-mode voltage range extending beyond the supply rails
• TTL- and CMOS-compatible output stage capable of driving standard logic loads
• Integrated shutdown control pin for reducing power consumption during idle states

Applications

• Automotive electronic systems
• High-speed instrumentation circuits
• Clock and data signal restoration
• Logic level shifting or translation
• Threshold detection and peak detectors

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status as indicated by the Z suffix in the part number. Ensure the SC-70 package orientation matches design requirements. Check for automotive qualification documentation if deploying in regulated environments. Validate datasheet revision against current manufacturing specifications.

Selection Notes

Select this component when rail-to-rail input capability is required with a single supply. Consider the 6-lead SC-70 package for space-constrained designs. Evaluate the shutdown feature for power-sensitive applications. Verify that the TTL/CMOS output compatibility meets downstream logic requirements. Assess thermal resistance characteristics for the specific PCB layout.

Part Context

This part belongs to the AD8468 series of fast, low-power comparators. It shares functional similarities with other members of the family but differs in packaging and ordering suffixes. The WBKSZ designation indicates the specific surface-mount package configuration. The R7 suffix denotes reel-based tape and reel packaging for automated assembly processes.

Replacement Considerations

Direct substitutes include the AD8468WBKSZ-RL variant, which offers identical electrical performance but utilizes tube packaging instead of tape and reel. Designers should verify pinout compatibility and package dimensions before substitution.
