Serial Control Data (Input/Output) - Bi-directional data I/O for the I²C control port.
Serial Data Input (Input) - Input channels serial audio data.
Frame Synchronization Clock/Left/Right Clock (Input/Output) - Determines which channel or
frame is currently active on the serial audio data line.
Master Clock (Input) -Clock source for the internal logic, processing, and modulators.
Serial Clock (Input/Output) -Serial Clock for the serial data port.
Serial Data Output 1 (Output) - ADC data output into a multi-slot TDM stream or AIN1 and AIN2
ADC data output in Left Justified and I²S modes.
Interface Power (Input) - Positive power for the digital interface level shifters.
Ground (Input) - Ground reference for the I/O and digital, analog sections.
Digital Power (Output) - Internally generated positive power supply for digital section.
Positive Analog Input (Input) - Positive input signals to the internal analog to digital converters.
The full scale analog input level is specified in the Analog Input Characteristics tables on pages
and 12.
Negative Analog Input (Input) - Negative input signals to the internal analog to digital converters.
The full scale analog input level is specified in the Analog Input Characteristics tables on pages
and 12.
Positive Voltage Reference (Output) - Positive reference voltage for the internal ADCs.
