5 MICBIAS Power Consumption

Table 5-1 and Table 5-2 describes the typical current consumption of the PCM6xx0 when the MICBIAS is turned on and a load is connected externally to the MICBIAS pin. Sampling frequency = 48KHz , BCLK/Fs = 192 , ADC and PLL are turned ON. The MICBIAS is turned on and programmed by:

Configuring the required voltage for MICBIAS in MBIAS_VAL field in the BIAS_CFG register.
Setting the MICBIAS_PDz bit in the PWR_CFG register.
