Power Supplies
Power Supply Current: VA+VD
Note: 2. Analog input voltage (full-scale voltage: IPGA = 0dB) scale with VREF. (IPGA = ADC = 0.6 x VREF)
Note: 3. ADC is input from LIN1/RIN1 or LIN2/RIN2 and it measures included in IPGA. The value of IPGA is set 0dB.
Note: 4. In case of power-down mode, all digital input pins including clocks pins (MCLK, BCLK and LRCK) are held
