inverting PGA | Cypress Semiconductor
im using a TIA and want to gain and invert that signal with a "inverting PGA". The gain works fine, but i cant invert the signal. No matter how i connect it or using a "PGA" or a "inverting PGA", the outputsignal is always negativ. I routed the signals via GPIO to an oscilloscope to opserve them. Whats wrong?
