TLV4170: TLV4170

Part Number: TLV4170
Other Parts Discussed in Thread: LM358, TIPD190, TIPD195

Dear sir,

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.

                             0-10V  input

           4-20mA input

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.

Thank you
