Infineon Technologies EVALAUDIOI2SCOM Evaluation Board

Infineon Technologies EVALAUDIOI2SCOM Evaluation Board is an I2S interface board designed for the EVALAUDIOMA12040P and EVALAUDIOMA1207P Class D audio amplifier boards. This evaluation board converts either analog or digital S/PDIF audio into an I2S format that matches the default settings of the EVAL_AUDIO_MA1240P/MA12070P boards. The EVALAUDIOI2SCOM evaluation board supports three different input signal options. These include analog audio-input via the onboard 3.5mm jack connector, digital audio-input via the onboard RCA connector, and digital audio-input via the onboard optical connector. This evaluation board offers I2S format digital output that seamlessly connects to the digital input Class D amplifier evaluation boards. The EVALAUDIOI2SCOM evaluation board operates within 3.1V to 3.5V supply voltage range and is available in 72mm × 64mm × 20mm dimensions.
