WM9712L
POWER CONSUMPTION
Production Data
w
PD Rev 4.0 December 2003
12
The power consumption of the WM9712L depends on the following factors.
Supply voltages: Reducing the supply voltages also reduces digital supply currents, and therefore results in significant
power savings especially in the digital sections of the WM9712L.
Operating mode: Significant power savings can be achieved by always disabling parts of the WM9712L that are not
used (e.g. audio ADC, DAC, touchpanel digitiser).
