Hi Chris,
Even though my ADS works great with the microcontroller, I was not able to cycle through 6 channels more than 600Hz. The biggest reason is that I have to mux between channels; and everytime I do so, I also have to send SYNC and WAKEUP Commands.
I wonder if it is possible to do the following:
1. I can replace the XTAL clock 7.68MHz on the board by a 10Mhz one.

2. I run the SPI speed at 5Mhz (half of the oscillation frequency
Ideally, I probably be able to increase the sampling rate to 800Hz. what else could I do?
Thanks,
Khoi Ly
