Application note

audio system demonstration board based on the STA335ML

Introduction

The STEVAL-CCA049V1 is a demonstration board designed for the evaluation of the

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.
