Function
Reference Input Voltage. The REF range is from 0.5 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.
Analog Input. It is referred to in –IN. The voltage range, i.e., the difference between +IN and –IN, is 0 V
to V
REF
.
Analog Input Ground Sense. To be connected to the analog ground plane or to a remote sense ground.
Power Supply Ground.
Chip Select Input. On its falling edge, it initiates the conversions. The part returns in shutdown mode as
soon as the conversion is done. It also enables D
OUT
. When high, D
OUT
is high impedance.
Serial Data Output. The conversion result is output on this pin. It is synchronized to SCK.
Serial Data Clock Input.
