    PSoC BLE - Opamp

    kiran.gopakumar

       Hello There;

         

      Good Day to all!

         

      In my application I'm using a PIR sensor, the output of the sensor is 1mVPP only, so I'm using 2 opamp to boost the signal to 3V and giving the 3V output to MCU to trigger. 

         

      In PSoC BLE block diagram  I saw 4 programmable opamp, can I use this inbuilt opamp to boost my sensor output signal? Did any one use this opamp for similar application?? If possible , then I can reduce my BOM price and can save PCB area! 

         

      Please help me by giving your suggestions!

         

       

         

      Best regards
