AD2428WCCSZ-RL

Overview

The AD2428WCCSZ-RL is an Automotive Audio Bus (A2B) transceiver manufactured by Analog Devices Inc. It supports master operation and connects to a single-master, multiple-slave A2B network with up to 15 meters between nodes. The device features a multichannel I2S/TDM interface supporting 8-bit to 32-bit resolution with up to 32 upstream and 32 downstream channels. It includes a PDM interface for four high dynamic range microphone inputs. Operating voltage ranges from 3V to 3.63V, with an operating temperature of -40°C to 105°C. It is housed in a 32-LFCSP-SS (5x5) package.

Feature Summary

• Configurable A2B bus master operation with support for up to 10 discoverable slaves
• Multichannel I2S/TDM interface with programmable data rates and up to 32 upstream/downstream channels
• Integrated PDM interface supporting up to four high dynamic range microphones
• I2C control interface with remote access capabilities over the A2B bus

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and AEC-Q100 qualification status for automotive grade requirements. Check moisture sensitivity level (MSL 3) handling instructions during storage and assembly. Ensure ordering suffix matches required packaging format such as Tape & Reel or Cut Tape.

Selection Notes

Select this transceiver when master node functionality is required within an A2B topology. Verify compatibility with host controllers via I2C and I2S/TDM interfaces. Consider power supply constraints as VIN must support 3.7V to 9.0V for internal regulators. Evaluate thermal dissipation requirements given the 32-WFQFN exposed pad package.

Part Context

This part belongs to the AD242x(W) series of Automotive Audio Bus transceivers. It shares architectural similarities with models like AD2420, AD2426, AD2427, and AD2429 but differs in master capability and slave discovery limits. The 'W' designation indicates specific electrical characteristics suitable for longer cable distances compared to non-W variants.

Replacement Considerations

Direct replacements within the same family include AD2429WCCSZ-RL which offers similar master capabilities but with different slave discovery limits. Cross-family substitution requires careful evaluation of pin compatibility and software configuration differences.
