Convert Input. On its leading edge, it initiates the conversions. It enables the SDO pin when low.
Serial Data Output. The conversion result is output on this pin. It is synchronized to SCK.
Function
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.
Analog Input. It is referred to in IN−. The voltage range, that is, the difference between IN+ and IN−, which
is 0 V to V
Analog Input Ground Sense. To be connected to the analog ground plane or to a remote sense ground.
Power Supply Ground.
Serial Data Clock Input. When CNV is low, the conversion result is shifted out by this clock.
