WM9715L  
Production Data  
POWER CONSUMPTION  
The power consumption of the WM9715L 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 WM9715L.  
Operating mode: Significant power savings can be achieved by always disabling parts of the WM9715L that are not  
used (e.g. audio ADC, DAC, touchpanel digitiser).
