Application note
STA350BW 2.0-channel demonstration board
Introduction
The purpose of this application note is to describe:
■ how to connect the STA350BW 2.0-channel demonstration board
■ how to evaluate the demonstration board performance with all the electrical curves
■ how to avoid critical issues in the PCB schematic and layout of the the STA350BW
The STA350BW demonstration board is specifically configured for 2.0 BTL channels,
releasing up to 2 x 50 W into 6 ohm of power output at 25 V of supply voltage using reduced
components. It is a complete solution for the digital audio power amplifier.
