I need ADC with really differential input and single supply.
-IN connected to reference point (REF/2)
+IN connected to input signal (+\- 2.5v)
I tried AD7684 but DataSheet tells that +IN and -IN MUST be in opposite phase to reference point. I used MCP3301 which is pin2pin compatible with AD7684 but allow any signals on inputs.
Now we need 500kS ADC and MCP3301 couldn`t achieve this.
Could you advice ADC or solution for AD7693 to adapt it to described use case.
Thank you in advance.
