DDAn
is the analog supply input pin for the eQADC_A.
VDDA_A1
V
DDAn
is the analog supply input pin for the eQADC_A.
REFBYPCA1
REFBYPCA1 is a bypass capacitor input for the eQADC_A. The REFBYPCA1 pin is used
to connect an external bias capacitor providing a stable reference voltage for the ADC.
VSSA_A1
V
SSAn
is the analog ground reference input pin for the eQADC_A.
VDDA_B0
V
DDAn
is the analog supply input pin for the eQADC_B.
VDDA_B1
V
DDAn
is the analog supply input pin for the eQADC_B.
VSSA_B0
V
SSAn
is the analog ground reference input pin for the eQADC_B.
REFBYPCB1
REFBYPCB1 is a bypass capacitor input for the eQADC_B. The REFBYPCB1 pin is used
to connect an external bias capacitor providing a stable reference voltage for the ADC.
