Hi,
Actually i just want to know if there is a bipolar signal is coming through feedback to ADC so which type of ADC should be used ,so if there bipolar ADC , quetion is how it works?
ADCs typically can be configured as bipolar. Some of the ADCs have the 'bipolar' pin as separate. You dont have to worry about it. If its bipolar, check out the codes, its going to givedigital '0000' for the max -ve value
