Pin Name

Pin Description

RST

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

M/S

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

LRCK

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

serial audio data line.

SCLK

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

MCLK

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

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

GND

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

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

SDOUT

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

MDIV

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

HPF

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

I2S/LJ

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.

OVFL

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

AINL+

AINL-

16,

Differential Left Channel Analog Input (Input) - Signals are presented differentially to the delta-sigma

modulators via the AINL+/- pins.

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

AINR-

AINR+

20,

Differential Right Channel Analog Input (Input) -Signals are presented differentially to the delta-sigma

modulators via the AINR+/- pins.

22 Quiescent Voltage (Output) - Filter connection for the internal quiescent reference voltage.

REF_GND

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

FILT+

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