Part Number: TIDA-00164
Good morning
I'm an italian engineer and I'm developing a data acquisition system for a company that manages waste water plants. My need is to acquire data from analog sensors and your ads8688 ADC seems
good for my application. Some time ago I checked you site and found your reference designed board (TIDA-01214) and asked some questions about it. But, searching again your site, I found your TIDA-00164 board and it seems to me a better solution to my problem.
My purpose is to integrate that board in the device I'm developing, which uses an ARM cortex CPU board with SPI interface.
My questions are:
1 - Do you confirm that it is possible to connect your board to a CPU by means the SPI bus?
2 - Is it possible to build the board using the ADS8688A instead of the ADS8688? The extended measurement range ±1.28 V, ±0.64 V of the ADS8688A would be useful to me, since some sensors generates an output signal in the range ±1.0V.
3 - Some sensors of mine generate an output signal in the range 4 - 20 mA. If I use the ADS8688A how do the board features change?
Thank you very much for your help.
Best regards.
