6. The PWM driver should be used in captive speaker systems only.
7. Optimal PWM performance is achieved when MCLK > 12 MHz.
8. VHP settings lower than VA reduces the headroom of the headphone amplifier. As a result, the DAC
written on power up.
Parameters
may not achieve the full THD+N performance at full-scale output voltage and power.
