Problem with GPIO s
hello to all,
I am using opamp in non inverting mode with Rf=1k, R=1k, feeding input to positive terminal of OPAMP. but problem is that with out input voltage the opamp generating output voltage of around 2v. and also from my design PGA input is given from OPAMP externally, here also with out external connection to PGA , PGA out put goes to 2.43v. i dont know i am doing wrong.here all PINS configured in highimpedance analog mode.
Uploading the work.
