Class d audio amplifier board

In most cases the power supply will need to have auxiliary low-voltage outputs (±12V, 5V, 3.3V, etc.) in addition to the main amplifier power output. At high output power, the auxiliary outputs can sag along with main audio output voltage, which can cause problems with tuners, motor drives, etc.For an audio amplifier with 10-W P LOADmax, an average P LOAD of 1 W can be considered a realistic listening level. Under this condition, 282 mW is dissipated inside the Class D output stage, vs. 2.53 W for Class B and 30.2 W for Class A. In this case, the Class D efficiency is reduced to 78%-from 90% at higher power. 3. Class D amps are extremely susceptible to hum on the power feeds to the amplifier. This is because the MOSFETs that do the switching are switching hard against the power rails and any AC voltage superimposed on these rails (ripple aka hum) gets transferred to the speaker. Best idea is to add more decoupling capacitors to the power supply ...MERUS™ class D audio amplifier ICs, multi-chip modules and discrete MOSFET/HEMT driver ICs. A traditional class D amplifier is a switching amplifier, usually consisting of two power MOSFETs with pulse-width-modulation (PWM) signal.
