Mr. Petkov Posted May 15, 2011 Report Share Posted May 15, 2011 Dear support engineers, Please let me know what is the actual input impedance of AN0 and AN1. The document "JZ10-11-R31_TECH-SPEC_ 06-06.pdf" claims it is 154 Ohm. A measurement with a multimeter shows 95.5 Ohm. The way to come at this point is, that we have a problem with a 4-20mA transmitter. The transmitter needs to have exactly 250 Ohm load, but we have Jazz R31 analog input. Please expain for me, ASAP. Kind regards, Petkov. Quote Link to comment Share on other sites More sharing options...
