AD2427WCCSZ-RL Description

Short technical summary and product information.

The AD2427WCCSZ-RL is a high-performance A2B (Automotive Audio Bus) audio transceiver designed by Analog Devices for automotive audio applications. It operates as a line topology bus with a single master and multiple slave nodes, allowing node-to-node distances up to 15 meters and a total cable length of 40 meters. This transceiver integrates I2C and multichannel I2S/TDM interfaces supporting 8-bit to 32-bit data formats. It provides 32 upstream and 32 downstream audio channels, along with a PDM interface capable of interfacing up to 4 digital microphones.

 

The device is AEC-Q100 qualified, ensuring reliability in demanding automotive environments. It operates over a wide temperature range of -40°C to +105°C and requires a supply voltage of 3.0V to 3.63V. The transceiver is surface-mount compatible with a wettable flank design, packaged in a compact 32-LFCSP-SS (5x5 mm) package. Its programmable settings allow optimization for electromagnetic compatibility (EMC) performance.

 

Typical applications include in-vehicle audio communication, hands-free systems, active noise cancellation, microphone arrays, and beamforming. The device can be configured using Analog Devices' SigmaStudio graphical software tool for easy system development.
