ADS1263: ADS1263 in single ended measurements..?

Ilkka Räisänen

Part Number: ADS1263

Hi,

How can I use ADS1263 in single ended measurements?

So that the one wire is in AIN0 and the second is in GND. What should be written into the registers?

I do not find that information in the documentation.

BR, Ilkka

Hi Ilkka Raisanen,

Refer to Table 7.3 ("recommended operating conditions") to check the absolute input range limitations. This will indicate that if you are using a unipolar supply (AVDD = 5V, AVSS = GND), then you can only measure ground-referenced input signals with the PGA bypassed.

Please also refer to section 10.1.2 ("single-ended measurements") for more information about level-shifting the negative input pin (AINN) to an offset voltage, which can allow a wider use of the ADC's full scale range compared to grounding the AINN pin.

Thanks, the single ended seems to work. I just connected AIN1 to ground. The measurements are more stable now.
