PVDD1 (Pin39), PVDD2 (Pin 46)
Note1: DVDD-IO must be lower than DVDD.
Note2: PVDD must be greater than AVDD. Keep PVDD ≥ AVDD+0.8V for best performance.
When (PVDD ≥ AVDD + 1V), THD+N will be degraded when playing at full power output.
Note3: When the Class-D amplifier is operating, surges of PVDD > 7V duration for 0.1ms may damage the amplifier. To
suppress such surges, 10µF tantalum capacitors are required at PVDD1 and PVDD2.
