Functions

74

EVRIN1R

AI

AI

Electronic volume input pin. Make sure to connect this pin with DACOUT1R

(DAC output) via coupling capacitor. When this pin is unused, leave it open or

connect it to GND via capacitor.

75

DACOUT1R

AO

AO

DAC analog output pin. (R-channel output)

When the output setting of DAC1 is OFF, the pin output becomes GND.

76

DACOUT1L

AO

AO

DAC analog output pin. (L-channel output)

When the output setting of DAC1 is OFF, the pin output becomes GND.

77

EVRIN1L

AI

AI

Electronic volume input pin. Make sure to connect this pin with DACOUT1L

(DAC output) via coupling capacitor. When this pin is unused, leave it open or

connect it to GND via capacitor.

78

EVROUT1L

AO

AO

Electronic volume output pin.

When the output setting of EVR1 is OFF, EVRIN1L input signal output to

EVROUT1L via 50k

 register.

79

AVB

CODEC Substrate GND pin.

Make sure to connect this pin to GND with low impedance. Note that when the pin is

open, latch-up may occur.

(Caution)

* Make sure to connect decoupling capacitor between VDD and VSS.

* The unused input pins that are not particularly specified above should be connected to GND.

* The unused output pins that are not particularly specified above should be left open

(do not connect to anything else).

* Make sure to connect AVB (#79) to GND.(When the pin is open, latch-up may occur).
