# Pin Description
1 Address Bit [0]/ Chip Select (Input) - Chip address bit in I²C Mode. Control signal used to select
the chip in SPI mode.
2 Address Bit [1]/ SPI Data Input (Input) - Chip address bit in I²C Mode. Input for SPI data.
3 Reset (Input) - The device enters a low power mode and all internal registers are reset to their
default settings when low.
4 Control Port Power (Input) - Determines the required signal level for the control port. See “Digital
I/O Pin Characteristics” on page 9.
5 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 inter-
face format.
6, 24 Digital Power (Input) - Positive terminal of the power supply for the digital section.
7, 23, Digital Ground (Input) - Ground terminal of the power supply for the digital section.
62
8 Serial Port Interface Power (Input) - Determines the required signal level for the serial interfaces.
See “Digital I/O Pin Characteristics” on page 9.
9 ADC Serial Clock (Input/Output) - Serial clock for the ADC serial audio interface. Input frequency
must be 256xFs in the TDM digital interface format.
10 Master Clock (Input) - Clock source for the Delta-Sigma modulators and digital filters.
13 Serial Audio Data Output (Output) - Outputs for two’s complement serial audio data.
