AD8129 Single Rail Supply

Hi

 

I am planning on configuring an AD8129 to run on a single supply of +5V and Ground with a gain of 10.

 

I am enquiring to the correct configuration of the circuit and specifically the gain resistor arrangement when -Vs is connected to ground. Is it the same circuit arrangement as when -Vs is connected to a negative supply rail (ie Rf/Rg = 9)?  Alongside this I plan to bias 4 (ref) at 2.5V. This question was briefly asked in topic (https://ez.analog.com/message/116994#116994) but did not result in a clear answer.

 

Any help would be much appreciated.

 

Regards

 

Charles
