AD2428WCCSZ01-RL

Overview

The AD2428WCCSZ01-RL is an Automotive Audio Bus (A2B) transceiver manufactured by Analog Devices Inc. It supports configurable master or slave operation within a single-master, multiple-slave topology. The device features a multichannel I2S/TDM interface supporting up to 32 upstream and 32 downstream channels with data widths of 8-bit to 32-bit. It includes a PDM interface for up to four high dynamic range microphone inputs. Electrical specifications include a digital core supply voltage of 1.7V to 1.98V, an I/O supply of 3.0V to 3.63V, and an operating temperature range of -40°C to 105°C. It is housed in a 32-LFCSP-SS package.

Feature Summary

• Configurable A2B bus master or slave operation
• Multichannel I2S/TDM interface with up to 32 upstream/downstream channels
• PDM interface supporting up to 4 microphone inputs
• I2C control interface with remote access capabilities

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm functional equivalence, as suffixes may indicate variations in packaging or qualification. Confirm that the component meets AEC-Q100 automotive qualification requirements if intended for automotive use. Ensure compatibility with the host controller's I2C addressing scheme and power supply rails before procurement.

Selection Notes

Select this component for applications requiring synchronous audio transmission over distances up to 15 meters between nodes. It is suitable for systems needing direct connection to DSPs, FPGAs, or PDM microphones without additional codecs. Consider the 32-LFCSP-SS package constraints and thermal dissipation requirements when designing the PCB layout for master or slave node implementations.

Part Context

This part belongs to the AD2420(W)/AD2426(W)/AD2427(W)/AD2428(W)/AD2429(W) series of A2B transceivers. The AD2428 variant specifically supports both master and slave functionality with full I2S/TDM support and four PDM microphone inputs, distinguishing it from variants limited to receiver-only or transmitter-only roles.
