Title: Unknown IC
Post by: fant on April 23, 2024, 09:12:25 pm

Good morning;
I am trying to fix a current calibrator, but i cannot find the model of the IC in picture.
Should be a D/A converter, from the function on the PCB.
Tho output is stuck at 0 Vdc and no current.
Any idea about the model?
Thank you in advance.
