Overview
The EVM demonstrates the TAS55548 device from Texas Instruments. The TAS55548 is an 8-channel
audio processor with ASRC and PWM output. This EVM has two outputs (Left and Right channels) via
3.5-mm headphone jack. For detailed information about the TAS5548 device, review the device data sheet
