(1) It is recommended for DVDD to be connected to DREG via a 100- resistor.
ELECTRICAL CHARACTERISTICS
PVDD_X = 23 V, GVDD = 23 V, DVDD = 3.3 V, DVDD connected to DREG via a 100-
resistor, RL = 6 , 8X fs = 384 kHz, unless otherwise
noted. AC performance is recorded as a chipset with TAS5010 as the PWM processor and TAS5122 as the power stage.
