Hi everyone,
I'm trying to connect an Olimex ADS1220 on my Raspberry Pi 4B.
I'm a beginner with this kind of SPI ADC and I don't really know how to properly wire it to the RPi. Particularly, I don't understand why there is two AVSS pins and where is the SCLK pin.
Thank you in advance for helping me !

The clock is CLK.
Just connect AVSS and GND to GND of the Pi 4B.
For VDD and AVDD connect them to the 3.3V of the Pi 4B.
