Serial Clock (Input) - Serial clock for the serial audio interface.
Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.
Serial Audio Interface Power (Input) - Positive power for the serial audio interface
Digital Ground (Input) - Ground reference for the digital section.
Step-up Charge Pump Cap Positive/Negative Nodes (Output) - Positive and Negative nodes for the
step-up charge pump’s flying capacitor.
Charge Pump and Digital Core Logic Power (Input) - Positive power supply for the step-up and invert-
ing charge pumps as well as the digital core logic sections.
Step-up Charge Pump Filter Connection (Output) - Power supply from the step-up charge pump that
provides the positive rail for the output amplifiers
Inverting Charge Pump Cap Positive/Negative Nodes (Output) - Positive and Negative nodes for the
inverting charge pump’s flying capacitor.
Charge Pump Ground (Input) - Ground reference for the Charge Pump section.
Inverting Charge Pump Filter Connection (Output) - Power supply from the inverting charge pump that
provides the negative rail for the output amplifiers.
Analog Outputs (Output) - The full-scale analog line output level is specified in the Analog Characteris-
tics table.
Pseudo Diff. Analog Output Reference (Input) - Ground reference for the analog output amplifiers.
This pin must be at the same nominal DC voltage as the AGND pin.
Analog Ground (Input) - Ground reference for the low voltage analog section.
