Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
Pin Description
Reset (Input) - The device enters a low power mode when low.
Master/Slave Mode (Input) - Selects operation as either clock master or slave.
Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the
serial audio data line.
Serial Clock (Input/Output) - Serial clock for the serial audio interface.
Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.
Digital Power (Input) - Positive power supply for the digital section.
Ground (Input) - Ground reference. Must be connected to analog ground.
Logic Power (Input) - Positive power for the digital input/output.
Serial Audio Data Output (Output) - Output for two’s complement serial audio data.
MCLK Divider (Input) - Enables a master clock divide by two function.
High Pass Filter Enable (Input) - Enables the Digital High-Pass Filter.
Serial Audio Interface Format Select (Input) -Selects either the Left-Justified or I²S format for the SAI.
Mode Selection (Input) - Determines the operational mode of the device.
Overflow (Output, open drain) - Detects an overflow condition on both left and right channels.
Analog Inputs (Input) - The full-scale analog input level is specified in the Analog Characteristics speci-
fication table.
Quiescent Voltage (Output) - Filter connection for the internal quiescent reference voltage.
Analog Power (Input) - Positive power supply for the analog section.
Reference Ground (Input) - Ground reference for the internal sampling circuits.
