7.1 Power supply bypass of HSA50 Pulse Width Modulation Amplifiers

HSA50 power supply should have plenty of bypass to ensure its correct operation, the +VS power supply should add a 1μF ceramic capacitor and parallel a low ESR value of bypass capacitor , the size of at least selected 10μf/ A .The VCC is the same need to parallel a 0.1 μF ceramic capacitor and a low ESR value of 6.8μF-10μF bypass capacitor . All bypass capacitors should be connected as close as possible to the corresponding power source.
