Other Parts Discussed in Thread: DAC161P997
Hello everybody
For a project in my company I am using the DAC161S997 to simulate a 4 to 20 mA interface. The Problem is that there is always the same current of 11.7 mA and this current depends on the resistor in the loop. I have used the circuit from the DS for the typical application. Another thing is that i don't measure any voltage at the base of the pzt3904 or over the resistor RE (In my scheme it's R10). I have configured the DAC with a write to the Err_config register with the value 0x035E and if I read the status_reg the DAC returns 0xE0 which should be totally fine.
