DESCRIPTION
When the ADC input mux is set to mic input to BOTH ADC channels, (SR2-0 and SL2-0 both set to ‘0’), one ADC is
shared between both channels and the other is powered off to save current. The same digital data is output to both slots.
The POP bit (reg 20h) also needs to be set for this mode.
These values are recorded with no external clocks applied to the WM9705.
Pen active duty cycle is approximately 10%. Average analogue current consumption is approximately 10% of stated figure.
