AD2426WCCSZ01

Overview

The AD2426WCCSZ01 is an Automotive Audio Bus (A2B) transceiver manufactured by Analog Devices Inc. It operates as a slave node within the A2B network, supporting multichannel I2S/TDM and Pulse Density Modulation (PDM) interfaces. The device features one functional transceiver block (TRX A only), enabling communication over distances up to 15 meters between nodes. It supports up to four PDM microphone inputs and provides configurable settings for electromagnetic compatibility optimization. The component is qualified for automotive applications and operates within a supply voltage range of 3V to 3.63V.

Feature Summary

• Configurable A2B bus slave operation with single TRX block
• Supports up to 32 upstream and 32 downstream I2S/TDM channels
• Integrated PDM interface for up to four high dynamic range microphones
• I2C control interface with remote access capabilities over the A2B bus

Applications

• Audio communication links in vehicles
• Microphone arrays and beamforming systems
• Hands-free and in-car communication modules
• Active and road noise cancellation units

Procurement Notes

Verify the specific ordering suffix '01' against the manufacturer's current datasheet to confirm package type and qualification status. Ensure the design accounts for the 32-LFCSP-SS package dimensions and thermal requirements. Confirm that the application utilizes the A2B protocol correctly for slave node integration.

Selection Notes

Select this component when a slave node configuration is required with support for up to four PDM microphones. It is suitable for applications needing up to 15-meter cable lengths between nodes. Compare with master-capable variants like the AD2428W if bidirectional bus control is needed. Ensure the system architecture aligns with the single TRX block limitation.

Part Context

This part belongs to the AD242x(W) family of Automotive Audio Bus transceivers. It shares the core A2B protocol implementation with other family members but differs in master/slave capability and transceiver block count. The AD2426W specifically lacks master functionality and has only one transceiver block, distinguishing it from dual-block or master-enabled counterparts.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing A2B network configurations before considering alternative components.
