AD2426WCCSZ-RL

Overview

The AD2426WCCSZ-RL 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 overall cable length. The device operates as a slave endpoint with one functional TRX block (TRX A only), lacking I2S/TDM support but including two PDM microphone inputs. It features a 32-LFCSP-SS (5x5) package, automotive grade qualification, and operates within a supply voltage range of 3V to 3.63V and temperatures from -40°C to 105°C.

Feature Summary

• Supports A2B line topology with up to 15m node-to-node distance
• Includes one functional TRX block (TRX A only)
• Provides two PDM microphone inputs via DRX0/IO5 pin
• Automotive qualified with -40°C to 105°C operating temperature

Applications

• Audio communication links in vehicles
• Microphone arrays for beamforming
• Hands-free and in-car communication systems
• Active and road noise cancellation modules

Procurement Notes

Verify the specific suffix 'W' indicates the enhanced version with improved receiver performance compared to standard variants. Confirm the 'RL' suffix denotes tape and reel packaging. Check current lifecycle status directly with Analog Devices or authorized distributors, as availability may vary by region and production batch.

Selection Notes

Select this model when a slave-only node configuration is required without local I2S/TDM processing capabilities. Ensure the system design accommodates the single TRX block limitation. Verify that the host controller can manage the A2B discovery process for up to 10 slaves if using a compatible master transceiver like the AD2428W.

Part Context

This component belongs to the AD242x(W) family of A2B transceivers. Unlike the AD2428W which supports both master/slave modes and full I2S/TDM interfaces, the AD2426W is restricted to slave operation with limited digital audio interface options. It shares the same physical package and basic electrical characteristics with other members of the series.

Replacement Considerations

Direct replacements within the same package include other AD242x(W) variants such as the AD2427W or AD2429W, provided the application does not require master functionality or additional TRX blocks. Verify register compatibility and firmware adjustments if swapping between different channel configurations.
