AD2425WCCSZ-RL

Overview

The AD2425WCCSZ-RL is an Enhanced Automotive Audio Bus (A2B) transceiver manufactured by Analog Devices Inc. It supports both master and slave operation within a single-master, multiple-slave topology. The device provides up to 32 upstream and 32 downstream multichannel I²S/TDM channels with programmable data rates. It includes four PDM inputs for high dynamic range microphones and features an embedded I²C control bus for remote register access. Operating at a supply voltage of 3.7V to 9V, it is qualified for automotive applications and functions within a temperature range of -40°C to 105°C.

Feature Summary

• Configurable as A2B bus master or slave
• Up to 32 upstream and 32 downstream I²S/TDM channels
• Four PDM microphone inputs
• Embedded I²C control and status information

Applications

• Automotive audio communication link
• Active noise cancellation
• Microphone arrays for hands-free and in-car communication

Procurement Notes

Verify the component status directly with the manufacturer, as lifecycle information may be subject to change. Confirm availability through authorized distributors. Ensure compliance with RoHS standards and check for specific packaging requirements such as Tape & Reel options when placing orders.

Selection Notes

Select the AD2425WCCSZ-RL when master node capability is required, distinguishing it from the AD2421W and AD2422W which are slave-only. Verify that the system design accommodates the 3.7V to 9V supply range. Ensure the application utilizes the I²S/TDM interface for synchronous data transmission over distances up to 15 meters between nodes.

Part Context

This component belongs to the AD242x series of A2B transceivers. It shares functional blocks with the AD2421W and AD2422W but adds master capability and I²S/TDM support. The suffix 'CCSZ' indicates the package type, while '-RL' denotes the reel packaging format.

Replacement Considerations

The AD2421W and AD2422W serve as compatible slave-only alternatives if master functionality is not needed. For systems requiring only slave operation, these parts offer similar channel counts and PDM input capabilities without the master configuration overhead.
