I need to tap an existing mixer circuit to obtain output for use in a second audio mixer circuit. I'm concerned about crossover between the two and plan to install a unity gain non inverting op amp (rigged single supply) as a buffer to prevent it. (Tapped audio signal from circuit 1 through the buffer to circuit 2 for mixing). Neither is high frequency, just mixed audio signal out of a couple of radios and another signal from a SM2166 mic pre-amp.
Is anything special required for this or would something basic like a UA741 work well enough? My supply is 5V.
All suggestions and or critique is welcome.
