Tool/software:
We are using ADS124S08 as multi channel ADC for different sensors. One of the sensors is PT100, it requires excitation current on AIN5. When I write 0x05 in IDACMUX register, I get excitation current on AIN5 and AIN0. I tried 0x50, 0xB0 and every time I got excitation current on AIN0 along with correct AIN. I tried different chips and result the same. When I try to turn on excitation on any AIN it turns on excitation on AIN0 as well. Is this correct behavior?
