APPLICATION INFORMATION
PCB MATERIAL RECOMMENDATION
FR-4 Glass Epoxy material with 2 oz. (70mm) is recommended for use with the TAS5611A. The use of this
material can provide for higher power output, improved thermal performance, and better EMI margin (due to
lower PCB trace inductance).
PVDD CAPACITOR RECOMMENDATION
The large capacitors used in conjunction with each full-bridge, are referred to as the PVDD Capacitors. These
capacitors should be selected for proper voltage margin and adequate capacitance to support the power
requirements. In practice, with a well designed system power supply, 1000mF, 50V will support more
applications. The PVDD capacitors should be low ESR type because they are used in a circuit associated with
high-speed switching.
DECOUPLING CAPACITOR RECOMMENDATIONS
To design an amplifier that has robust performance, passes regulatory requirements, and exhibits good audio
performance, a quality decoupling capacitors should be used. In practice, X7R should be used in this application.
The voltage of the decoupling capacitors should be selected in accordance with good design practices.
Temperature, ripple current, and voltage overshoot must be considered. This fact is particularly true in the
selection of the 2mF that is placed on the power supply to each half-bridge. It must withstand the voltage
overshoot of the PWM switching, the heat generated by the amplifier during high power output, and the ripple
current created by high power output. A minimum voltage rating of 50V is required for use with a 32.5V power
supply.
SYSTEM DESIGN RECOMMENDATIONS
The following schematics and PCB layouts illustrate best practices used for the TAS5611A.
