Function
1
REF
AI
Reference Input Voltage. The REF range is from 1 V to VDD. It is referred to the GND pin. This pin should be
decoupled closely to the pin with a ceramic capacitor of a few μF.
2
IN+
AI
Analog Input. It is referred to in IN. The voltage range, that is, the difference between IN+ and IN, which
is 0 V to VREF.
3
IN
AI
Analog Input Ground Sense. To be connected to the analog ground plane or to a remote sense ground.
4
GND
P
Power Supply Ground.
5
CNV
DI
Convert Input. On its leading edge, it initiates the conversions. It enables the SDO pin when low.
6
SDO
DO
Serial Data Output. The conversion result is output on this pin. It is synchronized to SCK.
7
SCK
DI
Serial Data Clock Input. When CNV is low, the conversion result is shifted out by this clock.
8
VDD
P
Power Supply.
1AI = analog input; DI = digital input; DO = digital output; and P = power.
