9 Power Supply Recommendations

The most important parameters are the absolute maximum rating on PVDD pins, bootstrap pins, and output pins. Over stress the device with higher that maximum voltage rating may shorten device lifetime operation and even cause device damage. Be sure that the specifications in Specifications are observed. For best audio performance, low ESR bulk caps are recommended. Depending on the application 470-µF capacitor or higher should be used. As always, decoupling capacitors must be placed no more than 1 mm from the power supply pins. If PCB space is not allowed for close placement of the decoupling capacitor, the decoupling capacitors can be placed on the back side of the device with vias. However, it still needs to be right below the pins.
