6.3.9 Power Tune Mode

For low power applications, the TAD5112-Q1 offers options to configure the device in a power tune mode with typical power consumption 10.5mW for 2-Ch playback for a 1.8V supply. This mode can be configured by setting the PWR_TUNE_CFG0 (P0_R78) register to 0xD4 and PWR_TUNE_CFG1 (P0_R79) register to 0x96. For power savings, the DAC modulator clocks are set to run at 1.536MHz (the input and output data sample rates are multiples or submultiples of 48kHz) or 1.4112MHz (the input and output data sample rates are multiples or submultiples of 44.1kHz). For more details refer the TAD5x1x Power Consumption Matrix Across Various Usage Scenarios application report for the supported settings in this mode.
