Pin Description
Serial Control Data (Input/Output) - SDA is a data I/O in I²C Mode. CDOUT is the output data line for
the control port interface in SPI Mode.
Serial Control Port Clock (Input) - Serial clock for the serial control port.
Address Bit 0 (I²C) / Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in I²C Mode;
CS is the chip-select signal for SPI format.
Address Bit 1 (I²C) / Serial Control Data Input (SPI) (Input) - AD1 is a chip address pin in I²C Mode;
CDIN is the input data line for the control port interface in SPI Mode.
Control Port Power (Input) - Determines the required signal level for the control port interface. Refer
to the Recommended Operating Conditions for appropriate voltages.
Reset (Input) - The device enters a low power mode when this pin is driven low.
Stereo Analog Input 3 (Input) - The full-scale level is specified in the ADC Analog Characteristics
specification table.
Stereo Analog Input 2 (Input) - The full-scale level is specified in the ADC Analog Characteristics
specification table.
Stereo Analog Input 1 (Input) - The full-scale level is specified in the ADC Analog Characteristics
specification table.
