Function
1
REF
AI
Reference Input Voltage. The REF range is from 0.5 V to VDD. It is referred to the GND pin. Decouple the
REF pin closely to the GND pin with a ceramic capacitor of a few μF.
2
+IN
AI
Analog Input. It is referred to Pin –IN. The voltage range, that is, the difference between +IN and –IN, is 0 V
to VREF.
3
–IN
AI
Analog Input Ground Sense. Connect this pin to either the analog ground plane or a remote sense
ground.
4
GND
P
Power Supply Ground.
5
CS
DI
Chip Select Input. On its falling edge, it initiates the conversions. The part returns to shutdown mode as
soon as the conversion is completed. It also enables DOUT. When high, DOUT is high impedance.
6
DOUT
DO
Serial Data Output. The conversion result is output on this pin. It is synchronized to DCLOCK.
7
DCLOCK
DI
Serial Data Clock Input.
8
VDD
P
Power Supply.
1 AI = analog input; DI = digital input; DO = digital output; and P = power.
