Part Number: TLV4170
We are started developing product based on TLV4170. We are designing analog card which is measure voltage 0-10V & 4-20mA.We attached both schematic with this thread.
We facing problem in 2 issues in both circuit.
First is, if not connect anything to input means input is open then some minor voltage generate at output of the OP-Amp.
Second is, We used ST microcontroller which as inbuilt 12bit ADC. When we start sampling of OP-Amp output then it's showing triangular wave in Oscilloscope & if we not sampling the OP-Amp output then showing constant voltage. In this issue if we used LM358 OP-Amp then this issue is not happen.We have very less knowledge about Analog design.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
