Forum Post: RE: ADS1243-HT : RREG command : Can I issue the command one time and keep reading out the register value to poll the DDRY bit status?

Hello Bob:

I have

range bit setting=1;

unipolar setting

Vref+ =2.5V, Vref-=0V

Gain setting=2

My understanding is that when

differential analog input=0V, then digital output  is zero

.differential analog input=negative,then digital output  is zero

differential analog input=2.5/4=0.625V, then digital output is 0xFFFFFF  ?

max offset voltage setting is: 2.5 /8=0.3125V

Is that right? Correct me if I am wrong

Thanks
