Application note
Sound Terminal^® 2.0-channel microless high-efficiency digital
audio system demonstration board based on the STA335ML
Introduction
The STEVAL-CCA049V1 is a demonstration board designed for the evaluation of the
STA335ML Sound Terminal^® high-efficiency digital amplifier. The purpose of this application
note is to show how to connect the 2.0-channel demonstration board and to explain how to
avoid critical board and layout issues.
The STEVAL-CCA049V1 demonstration board is configured for 2.0 BTL channels, releasing
up to 2 x 20 W into 8 Ω of power output at 18 V supply voltage in the PSSO36 slug-down
package. It represents a complete solution for a digital audio power amplifier capable of
operating without the aid of an external microcontroller.
