11 Power Supply Recommendations

The voltage source needed to power the PCM2903C must be between 3 V and 3.6 V for a proper operation. It is recommended to place decoupling capacitor in every voltage source pin. This will help filter lower frequency power supply noise. Place these decoupling capacitors as close as possible to the PCM2903C.
