Dear Sir,
Pleas give a solution.
I need negative signal feed to ADC channel.
One channel for Positive voltage +2 A7
Another channel for Negative -2 A6
Give me a solution
You can use OPA and bias voltage to convert the -2v signal to positive signal before feeding into the ADC input. After ADC conversion, substract the bias voltage to get the correct value.
Thanks,
Lixin
