  • 8-Channel Digital Amplifier Controller
  • “The control port has 2 modes: SPI and I2C, with the CS44800 acting as a slave device. SPI mode is selected if there is a high to low transition on the AD0/CS pin, after the RST pin has been brought high. I2C mode is selected by connecting the AD0/CS pin through a resistor to VLC or GND, thereby permanently selecting the desired AD0 bit address state.”
