My Customer intends to use the ADS8675 to measure 210 different analog channels through a multiplexer. The input range would need are +-10.24V, +-5.12V, +-2.56V. The channel measuring sequence requires measurement randomly change in-between the above 3 ranges for each MUX setting. It is a bit unclear how fast the PGA gain setting can be changed to a new setting with the build in 15 KHz antialiasing filter.
What are the shortest setup time in-between each measurement for the PGA setup and the assonated ADC conversion needed in order to achieve:
