    PSoC 6's  TIA

    user_496128763

      Hello.

       

      The PSoC 5LP's TIA(transimpedance amplifier) was very useful !!!!

       

       

      Now, PSoC 6 is Can use a TIA?

       

       

      I did not find anything related to the TIA in the PSoC 6 datasheet.

          Hello,

           

          PSoC 6 doesn't have the Switched Capacitor / Continuous Time (SC/CT) blocks found in PSoC 5LP, which can form TIAs without any external components. However, you can use the CTBm Opamps of PSoC 6 with external resistors to form TIAs. This configuration also provides better gain accuracy and linearity than SC/CT based TIA.

           

          Following image shows an example of PSoC 6  Opamp based TIA  feeding an ADC input. Note that you need to configure the "Output drive" option of the Opamp component to "Output to pin" to use this arrangement.
