Hi I would like to amplify a variable input voltage to a regulated 5 volt. Th e variable input voltage comes from the pulse coil my bike which is 50mv at low rpms and increases upto 30 volts at high rpms. The pulse goes to the P IC microcontroller. But the MCU requires 5 volt dc. So I thought of adding an op-amp in between the Pulse coil and the PIC MCU. If any body could help me with the schematics of it it will be gr8 for me. Eagerly Waiting for help, Cheers
