Forum Post: RE: ADS124S08: ADS124S08 Design Review
Hi Bob, I now use two IDACs for a 3-wire RTD. So I reduce the current from 1mA to 0.5mA and double the gain to 32. This way the circuit should work exactly the same as with a 2-wire RTD. The circuit...

Hi Jim, I'm agree with you, because I've observed that the delta phase between the two channels is constant. The problem is that this delta phase in not good for the system and I've tried to modify the...

My comment above about "pseudo-differential" input mode might be misguided. I am attempting to minimize CM noise that might enter the ADC from the field by doing a differential measurement. But as near...

Hi Khoi, To do that you need some way to translate voltage to current. That can be done with a series resistor between the voltage you want to measure and the DDC input. It is a bit tricky as the input...

Hello Luck, Thank you for your post! By default, the GPIO pins are configured as inputs. You can leave the pins configured as inputs and use a single 10-kOhm resistor to ground if they are unused. If...

Hello Rolek, Based upon your questions, I think you are asking for a fully differential input, which the ADS8166 does not support. You still keep the same full scale analog input range with either...
