AD2428WCCSZ02

Overview

The AD2428WCCSZ02 is an Automotive Audio Bus (A2B) transceiver from Analog Devices, designed for single-master, multiple-slave audio networks. It supports up to 15 meters between nodes and 40 meters total cable length. The device features a configurable master or slave operation with an I2C control interface. It provides an 8-bit to 32-bit multichannel I2S/TDM interface supporting up to 32 upstream and 32 downstream channels. Additionally, it includes a PDM interface for up to four high-dynamic-range microphone inputs. The component operates within a supply voltage range of 3.7V to 9V and is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

• Supports A2B line topology with up to 15m node-to-node distance
• Configurable as A2B bus master or slave node
• Multichannel I2S/TDM interface with up to 32 upstream/downstream channels
• Integrated PDM interface for four digital microphones

Applications

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

Procurement Notes

Verify the specific ordering suffix '02' against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required I/O voltage levels (1.8V or 3.3V) and VIN supply range (3.7V to 9V). Confirm that the automotive grade qualification meets the target application's reliability requirements.

Selection Notes

Select this transceiver for systems requiring master capability and support for four PDM microphones. Compare with AD2429W if only slave functionality and two discoverable slaves are needed. Ensure the design accommodates the 32-LFCSP-SS package dimensions and thermal dissipation requirements for the -40°C to +125°C operating temperature range.

Part Context

This component belongs to the AD242x(W) family of A2B transceivers. It shares core bus features with siblings like the AD2426W and AD2427W but is distinguished by its master node capability and specific PDM input count. The '02' suffix typically denotes a specific packaging variant within the standard AD2428W product line.

Replacement Considerations

The AD2429W is a related part within the same family but functions only as a slave and supports fewer discoverable slaves. Direct pin-for-pin replacement requires verifying master/slave role requirements and PDM channel counts.
