A2B audio transceiver for automotive cabin audio
The AD2426KCPZ is an A2B (Automotive Audio Bus) audio transceiver from Analog Devices, part of the Automotive series. It provides a single-channel digital audio link over a twisted-pair cable, using an I²C control interface and I²S audio data interface. The part operates from a 3V to 3.63V supply and is specified over the commercial temperature range of 0°C to 70°C.
The 3V to 3.63V supply range is a tight 3.3V nominal rail. The I²C bus handles register configuration and diagnostics; the I²S port connects directly to a codec or DSP audio serial port.
Temperature grade — deployment boundary
It is not rated for under-hood, engine bay, or exterior automotive locations where ambient exceeds 70°C. For those environments, the AD2426WCCSZ01 variant is rated -40°C to 105°C, and the AD2428BCPZ covers -40°C to 85°C.
Tray shipping is standard.
It is RoHS3 compliant. The AD2426WCCSZ01 offers the same function with wettable-flank terminals for automated optical inspection.
