AD2428WCCSZ01

Overview

The AD2428WCCSZ01 is an Automotive Audio Bus (A2B) transceiver designed for single-master, multiple-slave audio networks. It supports multichannel I2S/TDM and Pulse Density Modulation (PDM) interfaces, enabling up to 32 upstream and downstream channels with resolutions from 8-bit to 32-bit. The device operates within a supply voltage range of 3V to 3.63V and functions reliably across temperatures from -40°C to +105°C. Packaged in a 32-LFCSP-SS (5x5) format, it facilitates low-latency communication over distances up to 15 meters between nodes.

Feature Summary

• Configurable as A2B bus master or slave node with unique ID register support
• Supports up to 32 upstream and 32 downstream I2S/TDM channels
• Integrates PDM interface for up to 4 high dynamic range microphone inputs
• Enables GPIO and interrupt functionality over distance via embedded control frames

Applications

• Audio communication links in automotive systems
• Microphone arrays and beamforming applications
• Hands-free and in-car communication systems
• Active and road noise cancellation modules
• Audio/video conferencing systems

Procurement Notes

Verify the specific ordering suffix '01' against official Analog Devices documentation to confirm package type and temperature grade variations. Ensure compatibility with AEC-Q100 automotive qualification requirements if deploying in vehicle environments. Confirm surface mount installation methods compatible with wettable flank packages.

Selection Notes

Select this component for designs requiring robust A2B connectivity with integrated PDM microphone support. Verify that the host processor can manage the I2C configuration interface and I2S/TDM timing constraints. Ensure power supply rails meet the specified 3V to 3.63V range for both digital I/O and transceiver supplies.

Part Context

This part belongs to the AD2420(W)/AD2426(W)/AD2427(W)/AD2428(W)/AD2429(W) family of Automotive Audio Bus transceivers. It shares core architectural features with siblings like the AD2429W but differs in master capability and discoverable slave limits. The W suffix typically denotes enhanced performance characteristics compared to non-W variants.

Replacement Considerations

Direct substitutes within the same family include the AD2429WCCSZ01, which offers similar transceiver capabilities but may differ in master/slave configurations and cable length specifications. Cross-referencing the specific electrical characteristics and pinout compatibility is essential before substitution.
