ADVCM 28 O ADC comment mode voltage. It should be decoupled to AGND with a 22 uF in parallel
with a 0.1 uF. Signal level is AVDD/2.
AGND 29 GND Analog ground pin.
AVDD 30 +3.3V DAC power supply.
AOL3 31 O Analog left channel 3 output
AOR3 32 O Analog right channel 3 output
AOL2 33 O Analog left channel 2 output
AOR3 34 O Analog right channel 2 output
AOL1 35 O Analog left channel 1 output
AOR1 36 O Analog right channel 1 output
DAVCM 37 O DAC comment mode voltage. It should be connected to a 22 uF in parallel with a 0.1 uF
decoupling capacitors to ground. Signal level is AVDD/2.
DAVL 38, 39 GND DAC negative reference voltage. It should be tied to AGND.
DAVH 40,41 I DAC positive reference voltage. It should be connected to AVDD via a 180 ohm serial
resistor, and a 22 uF in parallel with a 0.1 uF decoupling capacitors to ground.
N/C 42 No connection. It can be tied to AGND.
