AD2427WCCSZ-RL

Overview

The AD2427WCCSZ-RL is an Automotive Audio Bus (A2B) transceiver from Analog Devices, designed for multichannel digital audio transmission. It supports single-master, multiple-slave topologies with up to 15 meters between nodes and 40 meters overall cable length. The device features a configurable A2B bus master or slave operation, supporting up to 32 upstream and 32 downstream channels via I2S/TDM interfaces. It includes a PDM interface for four high dynamic range microphone inputs and an I2C control port. Operating on a 3V to 3.63V supply, it is housed in a 32-LFCSP-SS (5x5) package and qualified for automotive applications.

• Active and road noise cancellation

Procurement Notes

Verify the specific ordering suffix and packaging configuration directly with Analog Devices or authorized distributors. Confirm that the component meets the required automotive qualification standards and operating temperature range for the intended application environment before finalizing procurement.

Selection Notes

Select this transceiver when a system requires both master and slave capabilities within the same node type or needs flexible topology configuration. Ensure the design accommodates the 32-LFCSP-SS package dimensions and thermal requirements. Verify compatibility with the host processor's I2C and I2S/TDM interface speeds and voltage levels.

Part Context

This component belongs to the AD242x(W) series of Automotive Audio Bus transceivers. It shares core architectural features with models like the AD2426, AD2428, and AD2429 but differs in functional TRX block availability and master/slave discoverability configurations as defined in the product comparison guide.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider verifying cross-compatibility within the AD242x family based on specific master/slave requirements and TRX block functionality.
