# Pin Description

1 Reset (Input) - The device enters a low power mode when low.

2 Master/Slave Mode (Input) - Selects operation as either clock master or slave.

3 Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the

serial audio data line.

4 Serial Clock (Input/Output) - Serial clock for the serial audio interface.

5 Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.

6 Digital Power (Input) - Positive power supply for the digital section.

7,18 Ground (Input) - Ground reference. Must be connected to analog ground.

8 Logic Power (Input) - Positive power for the digital input/output.

9 Serial Audio Data Output (Output) - Output for two’s complement serial audio data.

10 MCLK Divider (Input) - Enables a master clock divide by two function.

11 High Pass Filter Enable (Input) - Enables the Digital High-Pass Filter.

12 Serial Audio Interface Format Select (Input) -Selects either the left-justified or I2S format for the SAI.

13, Mode Selection (Input) - Determines the operational mode of the device.

14

15 Overflow (Output, open drain) - Detects an overflow condition on both left and right channels.

16, Analog Input (Input) - The full scale analog input level is specified in the Analog Characteristics specifi-

21 cation table.

17, Quiescent Voltage (Input/Output) - Filter connection for the internal quiescent reference voltage.

20,

22

19 Analog Power (Input) - Positive power supply for the analog section.

23 Reference Ground (Input) - Ground reference for the internal sampling circuits.

24 Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
