Hi,
Can any body out there tell me or any schematic how can I interface the Bi-polar signal (+/-1.5v ) signal to my 3.3 v adc working in unidirectional conversion(0-3v) Signal.
My signal varies +/-1.7v max from the 0v Reference
I wanted to shift the signal to a fixed level of 1.7v from the 0v reference
so that the signal should oscillate at the dc shift of 1.7v making +/- 3.4v from 0v reference
and then I can give to a unipolar adc (0 to 3.4v full scaled) for the conversion.
