AC constant current source |
Hi, I am trying to design an AC constant current source (1 mA p-p output) but facing many difficulties. I tried to build it as if it were a DC current source using instrumentation amplifiers(INA121P and OPA277P) (it worked perfectly for DC). As soon as I switch to an AC input voltage the circuit stops behaving as a constant current source. Is there a way I can get my AC current source? Thanx. M.Eid |

Dear M.,
I'm sorry but your question is outside the scope of this help desk. This help desk's goal is to assist people with communication cabling issues.
I found a number of power supply forums by doing an Internet search (I use Yahoo) and type in "Power Supply Forum". I think these groups would be better in answering your question.
Sincerely,
Joseph Golan, RCDD
