The AEK-AUD-C1D9031 integrates two audio amplifiers in stereo mode or two separate audio channels. The board compact size allows the designer to strategically place different modules around the vehicle to ensure that warning sounds can be heard along the entire vehicle length. All the modules can be controlled by a central MCU via CAN interface.
The embedded SPC582B60E1 microcontroller monitors and controls the two Class-D FDA903D power amplifiers driving the loudspeakers; the MCU sends the audio samples via I2S bus and programs the amplifiers via I2C interface.
