Adjusting Amplifier Gain in Hardware

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



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.
