Is it possible to put the PGA117AIPWR and the ADS1244 on the same SPI bus? If it is possible, how can I communicate without a CS line on the ADS1244?
Otherwise I may have to have an external switch for my own chip select line.
Thanks in advance

Hi HJ,
You could use the same bus but you would have to add some tri-state logic between the SPI bus and the ADS1244. The logic control would act similar to a CS. You could use something like the SN74LVC2G125.
