TYPICAL POWER MANAGEMENT MEASUREMENTS
Master clock = 12.288 MHz, integer PLL, input sample rate = 48 kHz, input tone = 1 kHz. Pseudo-differential input to ADCs, DACs to
line output with 10 kΩ load. ADC input @ 1 dBFS, DAC input @ 0 dBFS. In Table 4, the mixer boost and power management conditions
are set for MXBIAS[1:0], ADCBIAS[1:0], HPBIAS[1:0], and DACBIAS[1:0]. RBIAS[1:0] and PBIAS[1:0] do not have an extreme power
saving mode and are therefore set for power saving mode in the extreme power saving rows in Table 4.
