AD1928
CONTROL REGISTERS
DEFINITIONS
The format is the same for I
2
C and SPI ports. The global address for the AD1928 is 0x04, shifted left one bit due to the R/W bit. All
registers are reset to 0, except for the DAC volume registers that are set to full volume. Note that the first setting in each control register
parameter is the default setting.
