I'm building an amplifier from scratch directly based on the circuit for stereo as suggested in the TDA2009A, from ST. My question is related with the input voltage. It says in the datasheet that the input saturation voltage is 300mV.
My question is, is the input saturation voltage dependent from the gain and supply voltage and has to do with the overall amplifier saturation, or it is independent from any of those factors and has to do with the fact that the input transistors might saturate if this value is overlooked?
