AD2428WCCSZ

Specialized ICS Overview

The AD2428WCCSZ is an Automotive Audio Bus (A2B) transceiver manufactured by Analog Devices Inc. It supports a single master and multiple slave topology over distances up to 15 meters between nodes, with a maximum overall cable length of 40 meters. The device features an I2C control interface and handles multichannel I2S/TDM data with resolutions from 8-bit to 32-bit. It includes four PDM microphone inputs and supports bus power for subordinate nodes. Packaged in a 32-LFCSP-SS (5x5) case, it operates within the automotive temperature range.

Specialized ICS Feature Summary

• Configurable as A2B bus master or slave
• Multichannel I2S/TDM interface supporting up to 32 upstream and 32 downstream channels
• Integrated PDM interface for connecting up to four high dynamic range microphones
• I2C to I2C communication capability allowing remote register access over distance

Specialized ICS Applications

• Automotive audio communication link
• Active noise cancellation systems
• Microphone arrays for hands-free and in-car communication

Specialized ICS Procurement Notes

Verify package type and qualification status before ordering. Confirm that the specific revision matches design requirements. Check availability through authorized distributors. Ensure compliance with RoHS standards. Review datasheet for complete electrical specifications.

Specialized ICS Selection Notes

Select this component when A2B master functionality is required. Compare against AD2426W and AD2427W if only slave operation is needed. Consider cable length constraints and node count. Verify I2S/TDM channel requirements against the 32-channel limit. Ensure compatibility with SigmaStudio configuration tools.

Specialized ICS Part Context

This part belongs to the AD242x family of A2B transceivers. It shares the same package and basic interface features with the AD2426W and AD2427W. The primary distinction is its capability to function as the system master node, generating clocks and synchronization for the entire bus.
