AD2426WCCSZ

Overview

The AD2426WCCSZ is an Automotive Audio Bus (A2B) transceiver from Analog Devices, designed for single-channel audio applications in automotive environments. It operates within a supply voltage range of 3V to 3.63V and supports an operating temperature range of -40°C to 105°C. The device features I2C and I2S/TDM interfaces, enabling multichannel digital audio transmission over distances up to 15 meters between nodes. Packaged in a 32-LFCSP-SS (5x5) format with wettable flank capability, it is qualified to AEC-Q100 standards for automotive reliability.

Feature Summary

• Supports A2B line topology with single master and multiple slave configurations
• Enables synchronous data communication over distances up to 15 m per node
• Integrates I2C control interface and multichannel I2S/TDM data ports
• Qualified for automotive applications under AEC-Q100 standards

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 against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the host system's I2C addressing requirements and power supply specifications before procurement.

Selection Notes

Select this component for applications requiring A2B slave functionality with single TRX block support. Confirm that the system design accommodates the 32-WFQFN exposed pad package and meets the thermal dissipation requirements for the specified operating temperature range.

Part Context

This part belongs to the AD242x(W) family of Automotive Audio Bus transceivers. It is specifically designated as a slave-only device with one functional transceiver block, distinguishing it from master-capable variants like the AD2428W or AD2429W within the same series.

Replacement Considerations

Direct replacements within the AD242x(W) family require verification of master/slave capabilities and TRX block availability. Cross-referencing the specific pinout and electrical characteristics with the official datasheet is essential for any substitute selection.
