AD2426KCPZ

Overview

The AD2426KCPZ is an Automotive Audio Bus (A2B) transceiver from Analog Devices, designed for single-channel audio communication links. It operates within a supply voltage range of 3V to 3.63V and supports an operating temperature of 0°C to 70°C. The device features a 32-LFCSP (5x5) package with surface mount installation. It provides multichannel I2S/TDM interfaces with resolutions from 8-bit to 32-bit, alongside PDM microphone inputs. The transceiver enables synchronous data transfer over distances up to 15 meters between nodes, supporting both master and slave configurations within the A2B network topology.

Feature Summary

• Supports A2B bus line topology with up to 15 m node-to-node distance
• Configurable as A2B bus master or slave operation
• Multichannel I2S/TDM interface with 8-bit to 32-bit resolution
• Integrated PDM interface for high dynamic range microphone inputs

Applications

• Audio communication link
• Microphone arrays
• Beamforming
• Hands free and in car communication
• Active and road noise cancellation

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status via official documentation. Check moisture sensitivity level handling requirements during storage and assembly. Ensure ordering suffix matches specific automotive grade or temperature range requirements if applicable beyond standard industrial specs.

Selection Notes

Select this transceiver for applications requiring A2B connectivity with single-channel TRX functionality. Compare against AD2420, AD2427, AD2428, and AD2429 models based on master/slave capability and channel count. Ensure system power supply constraints align with the 3V to 3.63V operating range. Verify thermal dissipation capabilities for the LFCSP-32 package in enclosed automotive environments.

Part Context

The AD2426KCPZ belongs to the AD242x(W) family of Automotive Audio Bus transceivers. It shares architectural similarities with the AD2420, AD2427, AD2428, and AD2429 models but differs in functional TRX block availability and master/slave programmability. This specific part number denotes the commercial/industrial grade variant in the LFCSP-32 package, distinct from the wider temperature range W-series parts.

Replacement Considerations

Direct substitutes include other members of the AD242x(W) family such as AD2420, AD2427, AD2428, and AD2429, depending on required master/slave configuration and TRX block usage. Verify pin compatibility and software register mapping when migrating between these variants.
