I want to put the voltage and current output of the AD5422 on the same terminal.
There is a need for an OpAmp (AD5422 Datasheet, Figure 75) to buffer the +Vsense signal.
In the datasheet they suggest the OP184 or OP07 as buffer amplifier.
My application needs the 4-20mA and a 0-10V output. So I want to power the AD5422 with single power supply (AVSS = 0V = GND).
Can I use a single-supply OpAmp as buffer amplifier ? Do I need Rail-To-Rail input/output ?
What are the requirements for that OpAmp (rail-to-rail, precision, dual-supply, single-supply, etc) ?
