Hello,
I currently am trying to write to the PGA 0x2a and 0x09 (mux CH9 with gain 1). Here is the scope snapshot of what I am sending to the PGA:

However, I am unable to get anything out of Vout. On Page 27, there are SPI commands for the PGA112 and PGA113 but I don't see the commands for the PGA117. Are they the same? If not, where is the reference for the SPI commands to send to the PGA117. Thank you.
