USB audio demonstration board
Description
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 pre-
amplifier 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.
