Forum Post: RE: ADS1256: Power Drain during channel switching
Hi Chris, Sorry for the delayed response. The scope capture was battery voltage and 3.3V rail We had probed the 5V rail and did not see the dip on the rail. Hence it is not the ADS1256 which is...

Joseph, In this case. My customer is measuring voltage between -2.5V to +2.5V. Then I think that we could use +2.5V LDO to AVDD, -2.5V LDO to AVSS, then use a 5V reference like REF5050 connect to...

Hi Jim, I'm sorry, but your answer makes no sense, because: 1. I can get the full Fourier transform data, which takes twice as much memory (for a complex transform). 2. It is always the responsibility...

Thank you! But the max input range is not dictated by HVDD and HVSS? Which would mean that I could achieve plus minus 15 V as input range? Besides, my worries were not to damage the converter by...
