Other Parts Discussed in Thread: PGA309
Hello there
I have a XTR111 based, 3-wire 4-20mA transmitter on a custom converter and I found a problem with resistance load's of loop current higher than ~60R. The problem is: With resistance higher than 60R, the current drops to ~2.8mA instead 4mA, and ~5mA instead 20mA. Without 60R load it works properly.
Can anyone help me? It's urgent.
Below the schematic. (VIN is the same at anytime).
Best Regards,
Leonardo Trinta
