Description
38, 39
PLL_MODE0,
PLL_MODE1
D_IN
PLL Mode Setting. These pins set the output frequency of the master clock PLL. See the
Setting Master Clock/PLL Mode section for more details.
40
CM
A_OUT
1.5 V Common-Mode Reference. A 47 μF decoupling capacitor should be connected
between this pin and ground to reduce crosstalk between the ADCs and DACs. The material of
the capacitors is not critical. This pin can be used to bias external analog circuits, as long as
those circuits are not drawing current from the pin (such as when the CM pin is connected
to the noninverting input of an op amp).
41
FILTD
A_OUT
DAC Filter Decoupling Pin. A 10 μF capacitor should be connected between this pin and
ground. The capacitor material is not critical. The voltage on this pin is 1.5 V.
43
VOUT3
A_OUT
VOUT3 DAC Output. The full-scale output voltage is 0.9 V rms. This output can be used with
an active or passive output reconstruction filter. See the Audio DACS section for details.
44
VOUT2
A_OUT
VOUT2 DAC Output. The full-scale output voltage is 0.9 V rms. This output can be used with
an active or passive output reconstruction filter. See the Audio DACS section for details.
45
VOUT1
A_OUT
VOUT1 DAC Output. The full-scale output voltage is 0.9 V rms. This output can be used with
an active or passive output reconstruction filter. See the Audio DACS section for details.
46
VOUT0
A_OUT
VOUT0 DAC Output. The full-scale output voltage is 0.9 V rms. This output can be used with
an active or passive output reconstruction filter. See the Audio DACS section for details.
47
FILTA
A_OUT
ADC Filter Decoupling Pin. A 10 μF capacitor should be connected between this pin and
ground. The capacitor material is not critical. The voltage on this pin is 1.5 V.
1 PWR = power/ground, A_IN = analog input, D_IN = digital input, A_OUT = analog output, D_IO = digital input/output, D_IO/A_IO = digital input/output or analog
input/output.
