Abstract

Updated PCB captures display improved GND connection on Pin 28

In audio applications, it is always important to minimize the noise effects that may be induced by external conditions or even by the same components of the PCB. All the audio amplifiers require a clean and stable power supply to get the best performance. Any noise issue at the power supplies may be the cause of a high THD+N and SNR levels. In addition, the analog inputs and outputs require good noise immunity against the digital activity from nearby devices.

This document describes an optimized layout for the TAS2x63 device in mono configuration. The goal of utilizing these layout guidelines is to minimize the noise issues and ensure the best device performance.

The TAS2x63EVM was taken as reference for the suggested guidelines.
