Pin Description
Serial Control Data (Input/Output) - Bidirectional data line for the I²C control port.
Serial Control Port Clock (Input) - Serial clock for the I²C control port.
Control Port Power (Input) - Determines the required signal level for the control port interface. Refer to
the Recommended Operating Conditions for appropriate voltages.
Reset (Input) - The device enters a low-power mode when this pin is driven low.
Analog Power (Input) - Positive power for the internal analog section.
Analog Ground (Input) - Ground reference for the internal analog section.
Analog Input (Input) - The full-scale level is specified in the ADC Analog Characteristics specification
table.
Signal Ground (Input) - Ground reference for the analog line inputs.
Antialias Filter Connection (Output) - Antialias filter connection for the ADC inputs.
Quiescent Voltage (Output) - Filter connection for internal quiescent voltage.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
Microphone Input (Input) - The full-scale level is specified in the ADC Analog Characteristics specifica-
tion table.
Microphone Bias (Output) - Low noise bias supply for external microphone. Electrical characteristics
are specified in the DC Electrical Characteristics table.
