Class-D Amplifier Circuits Design Considerations for Class-D Audio Power Amplifiers 3 The internal gain of the class-D amplifier limits the input voltage to a maximum of VIN PO RL AV where PO is the maximum output power, R L is the dc load resistance, and A V is the internal gain of the class-D amplifier. The large gain and low input currents

Class D amplifier reference design with GaN FETs from Efficient Power Conversion (Image: Renesas) Eradicating EMI. Expecting to eradicate electromagnetic interference (EMI) may be overly optimistic for a high-frequency power switching Class D amplifier design. But managing and controlling EMI is possible, and can also be very important for noise-sensitive …

This report uses TAS5805M as an example to discuss thermal design considerations in Class-D audio amplifiers. The report analyzes the thermal problems in TAS5805M from two aspects: power losses and heat dissipation. To reduce power losses, some factors need to be taken into account, such as switching

Basic Elements of a Class D Amplifier The basic principle of Class D is to operate the “switches” at a frequency much higher than the audio range so that the re-sulting pulses can be filtered and smoothed out leaving only the desired audio signal. This takes three major processing blocks plus important error correction and protection systems
