AD2429WCCPZ01

Overview

The AD2429WCCPZ01 is an Automotive Audio Bus (A2B) transceiver from Analog Devices, designed for single-master, multiple-slave audio communication systems. It supports up to two discoverable slave nodes with a maximum node-to-node cable length of 5 meters. The device features a configurable A2B bus master or slave operation, supporting multichannel I2S/TDM interfaces with 8-bit to 32-bit data widths and up to 32 upstream/downstream channels. It includes a PDM interface for four high dynamic range microphone inputs. Operating within a supply voltage range of 3V to 3.63V and an industrial temperature range of -40°C to +105°C, it is housed in a 32-LFCSP package.

Feature Summary

• Configurable A2B bus master or slave operation with support for up to 2 discoverable slaves
• Multichannel I2S/TDM interface supporting 8-bit to 32-bit data widths and up to 32 upstream/downstream channels
• Integrated PDM interface for direct connection of up to four high dynamic range microphones
• Automotive grade qualification (AEC-Q100) with operating temperature range of -40°C to +105°C

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm that the specific ordering suffix matches the required package and temperature grade. Check for any product discontinuance notifications or end-of-life status updates prior to finalizing procurement plans.

Selection Notes

Select this model when designing A2B networks requiring master functionality with limited slave expansion (up to 2 nodes). Ensure the application utilizes short cable runs (max 5m between nodes) as specified for the AD2429 variant. Verify compatibility with the host processor's I2C and I2S/TDM interface requirements.

Part Context

This component belongs to the AD242x(W) family of Automotive Audio Bus transceivers. It shares core architectural features with models like the AD2428W but differs in functional TRX block availability and slave discovery capacity. The 'W' suffix typically denotes automotive-grade variants within this series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices for current alternative recommendations if this obsolete part is no longer sourced.
