Address Bit [0]/ Chip Select (Input) - Chip address bit in I²C Mode. Control signal used to select
the chip in SPI Mode.
Address Bit [1]/ SPI Data Input (Input) - Chip address bit in I²C Mode. Input for SPI data.
Reset (Input) - The device enters a low power mode and all internal registers are reset to their
default settings when low.
Control Port Power (Input) - Determines the required signal level for the control port. See
I/O Pin Characteristics” on page
ADC Left/Right Clock (Input/Output) - Determines which channel, Left or Right, is currently
active on the ADC serial audio data line. Signals the start of a new TDM frame in the TDM digital
interface format.
Digital Ground (Input) - Ground terminal of the power supply for the digital section.
Serial Port Interface Power (Input) - Determines the required signal level for the serial inter-
faces. See
ADC Serial Clock (Input/Output) - Serial clock for the ADC serial audio interface. Input frequency
must be 256xFs in the TDM digital interface format.
Master Clock (Input) - Clock source for the delta-sigma modulators and digital filters.
Serial Audio Data Output (Output) - Outputs for two’s complement serial audio data.
