Product Number: AD5700
We have a 4..20mA loop powered HART-enabled device. We are used schematics from AD5700 specs for signal part. All working fine and we have supply voltage near 13V on 4mA. But during current rising to 20mA we have a drop near 2V on 110 Ohm resistor (I know that it should be more than 230 Ohm...). So it is not asccept requirements of customer, we need to stay on 13V level. I will appreciate any comment or help how to decrease value of load resistor and save HART communication. Thanks in advance!
