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 V_CC = 36 V and a 4 Ω load^(a).
