The circuit is almost a copy from page 6 of the specification.
The Vref provides 3.3V which makes the 4mA.
The Voltage applied thru R85 is 0 - 10Vdc, or 0 - 16mA, as the XTR117 would interpret.
What is not shown here is a 250 ohm resistor, from Pin 4 I-O to DGND.
As you can tell, the circuit has 15Vdc provided thru D19.
Pin 7 = 14.62Vdc
Pin 6 = 3.708Vdc
Pin 5 = 3.068Vdc
Pin 4 = 0.015Vdc
The idea is, 4 to 20 mA translates to 1 to 5Vdc thru a precision 250 ohm Resistor.
And I am connecting the Resistor directly to Pin 4, and avoiding the Bridge.
Why is there no output?
