Posted on May 17, 2011 at 09:49Hi,
Have anyone evaluated STR9 comstick's ADC.The digital o/p is 03ff when my analog input is only 2V.On the datasheet. it states the range is between 0 and 3.6. It seems like the ref voltage is at 2 but the schematic give a 3.3 V ref. Even at 0 input it yield a large output.
Did anything go wrong somewhere?
Thanks in advance for any help.
