Adjusting Amplifier Gain in Hardware

Version 1
    Question: Can I adjust the Programmable Gain Amplifier's gain with hardware?

     

    Answer:

    No. Resistor taps or capacitor ratios determine the gain on PSoC amplifiers. It can only be configured by programming the appropriate register bits. If the application requires a General Purpose OPAMP then SC Block can be make to worklike a FAUX Opamp. For details on this please refer to Application Note: AN2223.
