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 “Dig-
ital I/O Pin Characteristics” on page 8.
ADC Left/Right Clock (Input/Output) - Determines which channel, Left or Right, is currently
5 active on the ADC serial audio data line. Signals the start of a new TDM frame in the TDM digital
interface format.
6, 24 Digital Power (Input) - Positive terminal of the power supply for the digital section.
7, 23 62 Digital Ground (Input) - Ground terminal of the power supply for the digital section.
8
Serial Port Interface Power (Input) - Determines the required signal level for the serial inter-
faces. See “Digital I/O Pin Characteristics” on page 8.
9
ADC Serial Clock (Input/Output) - Serial clock for the ADC serial audio interface. Input fre-
quency must be 256xFs in the TDM digital interface format.
10 Master Clock (Input) - Clock source for the delta-sigma modulators and digital filters.
11
Test Out - This pin is an output used for test purposes only. This pin must be not be connected
to any external trace or other connection.
13
12
Serial Audio Data Output (Output) - Outputs for two’s complement serial audio data.
