CS4525 2.0 layout reference and guidelines

Class D amplifiers have several advantages over traditional Class A/B amplifiers. These include higher operating efficiencies, less thermal dissipation, and smaller form factors. However, in order to realise these advantages some changes are required relative to a traditional Class A/B amplifier board design. The board design changes are not difficult to implement, but are less familiar to most designers than techniques used for Class A/B amplifiers. Careful consideration to the circuit board layout should be taken up front in order to ensure a successful design.

This application note addresses the layout guidelines and provides layout references specific to the Cirrus Logic CS4525. The CRD4525-Q20 board is used as a layout example for a 2.0 speaker output configuration of the CS4525. This board should be used as a reference for all 2.0 speaker output configuration designs using the CS4525.

This application note is divided into three major sections. Section 1 is an overview of the high level board design subjects and how to get started. Section 2 and Section 3 focus on the component placement and board layout specific to a 2 channel, 2.0 output configuration, full-bridge board design, using the CRD4525-Q20 board as a reference. Component placement is discussed separately from layout and routing.
