Reset Pin
The device is powered down except for VCOM when this pin is “L”. All
registers are cleared and are set to default values.
Power down Pin
All blocks including VCOM are powered down when this pin is set to “L”.

Audio ADC Serial Data Output
Audio data Serial Output/Input Clock : 32fs
The device outputs ADC data through SDO pin at the falling edge of SCLK
clock. The device latches DAC (input) data through SDI pin at the rising
edge of SCLK clock.
Left/Right channel Select Clock, 1fs
H: Left channel, L: Right channel
When both of ADC block and DAC block go into power-down mode, this pin
outputs “L”. Either of block is active, the device outputs LRCK clock.
Audio DAC Serial Data Input
Master Clock Input
256fs or 512fs, which is selected by MSEL bit in the Control Register, master
clock is input to this pin.
DAC Left Channel Analog Output
Note) Load resistance must be greater than 10K
. Load capacitance must
be less than 50pF.
DAC Right channel Analog Output
Note) Load resistance must be greater than 10K
. Load capacitance must
be less than 50pF.
Analog Common Voltage Output
Reference voltage of all analog circuit block (VA/2)
Connect 4.7uF and 0.1uF capacitors
Analog Common Voltage Output for ADC
Reference voltage of ADC block
Connect 4.7uF and 0.1uF capacitors
Anti aliasing Filter for A/D Input
Connect 1nF capacitor.
Analog Input
Input inverting analog signal which is output from MICOUT pin
1uF capacitor is connected between MICOUT pin and AIN pin.
Microphone Analog Output
Output inverting analog signal with 20dB gain of MICIN signal.
Microphone Analog Input
Input analog signal from microphone
