Function
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.
Analog Input. It is referred to Pin –IN. The voltage range, that is, the difference between +IN and –IN, is 0 V
to V
Analog Input Ground Sense. Connect this pin to either the analog ground plane or a remote sense
ground.
Power Supply Ground.
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 D
Serial Data Output. The conversion result is output on this pin. It is synchronized to DCLOCK.
Serial Data Clock Input.
