DESCRIPTION
T
The data presented here was measured with the audio interface in master mode whenever the internal clock oscillator
was used, and in slave mode whenever an external clock was used (i.e. MS = 1 when OSCPD = 0 and vice versa).
However, it is also possible to use the WM8731 with MS = OSCPD = 0 or MS = OSCPD = 1.
All figures are quiescent, with no signal.
The power dissipation in the headphone itself not included in the above table.
