We are working on ADuC7060 software development for our product. We are reading +70mV acros ADC0:ADC1 in unipolar mode, internal reference (1.2V) with PGA to 16 and the results are erratic...But when we set the gaint to 1 or 2 the readings are good as expected. The gain set problem starts from PGA for 4 onwards, the ADC shows full value for 680mV instead of 300mV..... Is there any of the settings are we need to do apart from this...
Also let know what is in-amp as shown in the attached sheet???
