STEVAL-CCA021V1 USB audio demonstration board based on the STM32F103RE and TS4657

The STEVAL-CCA021V1 demonstration board implements a USB audio card based on the STM32F103RE microcontroller and the TS4657 audio digital-to-analog converter (decoder). The complete system consists of a controller board driven by the STM32F103RE microcontroller, and a TS4657-based audio board.

Mono audio output is available either through the TS4962-driven on-board speaker or via the mono jack connector, and stereo output is possible through the TS2012 stereo audio amplifier which can drive external speakers. Both audio amplifiers are class D.

For audio input, an on-board microphone is connected through the TS472 microphone preamplifier to the ADC input of the microcontroller. It is possible to disconnect the controller section from the audio section to use the boards individually for other applications.
