Hi every body,
I was making test on an inverter configuration op amp (picture atached) but mi gain calculations are not ok under 500Hz the gain start to go down.
As I think I make the calculation of the condenser to have an hight pass filter with cut frecuenci on 159 Hz but the gain until 400 or 500 hz are smaller than the teorical gain.
I was testing different op amps: TLV2264; MCP6022
Any body know witch could be the reason.????
I would like to have a linear amplifier betwing 160 Hz and 20 Kz.
