Low cost, precision 4...20mA loop powered display(2)
Additional information and documents of the old project presented in 2013
Instead of U1, you can use any type of low-consumption CMOS op-amp, such as "TS271N" from ST.
In this case, according to the data sheet, the resistor (R4) should be replaced with a value of about 4.7 to 8.2 Mega OHM.
