    Hi Thomas, Thanks for your reply I am not clear with the second idea that if output become open circuit the developed voltage would be enough to send the amplifier in to shutdown mode. That means OPA548 is having internal open load protection ? Other wise we need to use the open circuited...

    Hi Thomas, It is ok after rectifying the output voltage when inthe case of open circuit load operation the rectified DC output voltage is enough to send the amplifier in to shutdown mode. But without rectifying the Output voltage any alternate solution is available to protect from the Open load...

    Eduardo, It's not clear how 50nA of DC current would allow single supply operation. Did you mean 500nA? What is the impedance of your load? A Howland type current source is probably good solution. There are various postings on Howland current sources that may help. If you provide more details...
