I'm having trouble configuring the ADS8691 for 0-5.12V input range. I can correctly readout the ADC value, but it stays in -12V - +12V range, whatever I do.
Here are some scope shots of the configuring (sorry, I could not attach all 4 probes because the testpoints were forgotten) :
yellow: CS/Convst, magenta: SCLK
yellow: SCLK, magenta: SDI
yellow: SCLK, magenta: SDO
Can you help me on what I'm doing wrong?
Kind regards
Claudio
