AD2420WCCPZ01-RL

Overview

The AD2420WCCPZ01-RL is an Automotive Audio Bus (A2B) transceiver designed for low-cost audio bus slave applications. It supports a single channel with I2C and I2S/TDM interfaces, operating within a supply voltage range of 3V to 3.63V. The device is qualified to AEC-Q100 standards and functions reliably across an industrial temperature range of -40°C to +105°C. Packaged in a 32-LFCSP (5x5) surface-mount format, it facilitates synchronous multichannel audio transmission over twisted-pair cabling.

Feature Summary

• A2B Slave Transceiver: Supports single-master, multiple-slave line topology with up to 15 m node-to-node cable length.
• Audio Interfaces: Features 8-bit to 32-bit multichannel I2S/TDM interface and support for up to two PDM microphone inputs.
• Automotive Grade: AEC-Q100 qualified with an operating junction temperature range of -40°C to +105°C.
• Control & Communication: Includes I2C interface for register access and GPIO capabilities for inter-node communication.

Applications

• Automotive audio communication links
• Microphone arrays and beamforming systems
• Hands-free and in-car communication modules

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific revision level matches design requirements, as datasheet specifications are subject to change without notice. Ensure proper handling procedures for ESD-sensitive components during storage and assembly.

Selection Notes

Select this model for applications requiring a dedicated A2B slave node with limited channel count. Compare against AD2426W/AD2427W variants if higher cable lengths or additional functional TRX blocks are needed. Ensure the host system provides the necessary I2C addressing configuration via ADR1/IO2 and ADR2/IO2 pins.

Part Context

This component belongs to the AD2420(W)/AD2426(W)/AD2427(W)/AD2428(W)/AD2429(W) family of Automotive Audio Bus transceivers. It is specifically designated as a slave-only device, distinguishing it from master-capable models like the AD2428W. The 'W' suffix indicates enhanced performance characteristics compared to non-W variants.

Replacement Considerations

Direct pin-compatible replacements within the same family include AD2426WCCPZ01-RL and AD2427WCCPZ01-RL, though functional differences exist regarding master capability and cable length support. Cross-family substitution requires careful evaluation of interface compatibility and power requirements.
