Application note

Dual-BTL class-D audio amplifier demonstration board

based on the TDA7498E

Introduction

The purpose of this application note is to describe:

■ how to connect the TDA7498 demonstration board

■ how to evaluate the performance of the demonstration board using the electrical curves

■ how to avoid critical issues in the PCB schematic and layout of the TDA7498E

The TDA7498E represents a new generation of analog input class-D devices from

STMicroelectronics and is housed in a PSSO36 package. It is able to deliver 160 W +160 W

in stereo configuration with VCC = 36 V and a 4 Ω load
