Tool/software:
I am putting ADS8694 in one of my design.
The input is bipolar from -2V to 2V. and i am using the internal reference 4.096V with input range setting 0.625 x 4.096= +/-2.54V.
out of 18 bit data output 16 bit are changes as per input changes. but the 2 bits remains unchanged as input varies.
I am not getting why these two bits remains unchanged.
Please suggest the solution.
Hi Swapnil,
Can you tell us which ADC channel(s) you are seeing this behavior on? A schematic and o'scope or logic analyzer plots showing the control lines would be helpful if you can provide them.
