WM8750L
Production Data
POWER CONSUMPTION
The power consumption of the WM8750L depends on the following factors.
Supply voltages: Reducing the supply voltages also reduces supply currents, and therefore results in significant power
savings, especially in the digital sections of the WM8750L.
Operating mode: Significant power savings can be achieved by always disabling parts of the WM8750L that are not
used (e.g. mic pre-amps, unused outputs, DAC, ADC, etc.)
