When I will send serial data to SDI pin when the CS pin is High, will the pin SDO send the serial data?

Hello Janusz,
If the /CS pin is high, then SDO is in a high impedance state and will not have any output if you send data to SDI. You must first bring /CS low if you wish to communicate with the PGA23xx.

Thx for answer.
I want comunicate with three PGA23xx separately, so I thought I can connect the first PGA with de second and (SDO-SDI) and with CS terminal choose active IC. So I must do it different :)
best regards
