The basic module is powered by three separate power supply units. These form the symmetrical power supply stage, which is responsible for supplying each of the DAC chips with clean power. The DVCC, FCCA and AVCC rails are isolated. It is therefore possible to supply them independently with 3.3V / 100mA (minimum) for optimum performance, or to bridger them to use only one power supply. It is recommended to supply the DAC directly with 3.3V supercapacitor modules or LiFePO4 batteries, to obtain the best possible sound reproduction.
The 9038Q2MPi consumes about 50mA on average, with the MCLK 50MHz in asynchronous mode (default).
