NAME
FUNCTION
1
INA-
Channel A Negative Analog Input. For single-ended operation, connect INA- to COM.
2
INA+
Channel A Positive Analog Input. For single-ended operation, connect signal source to INA+.
3, 5, 10
GND
Analog Ground. Connect all GND pins together.
4
CLK
Converter Clock Input
6
INB+
Channel B Positive Analog Input. For single-ended operation, connect signal source to INB+.
