POWER CONSUMPTION
The power consumption of the WM8751L depends on the following factors.
• Supply voltages: Reducing the supply voltages also reduces supply currents, and therefore results in significant power
savings.
• Operating mode: Power consumption is lower in mono modes than in stereo, as one DAC is switched OFF. Unused
analogue outputs should be switched off.
