Hello, In short I need some formula that adjust the gain according to different output load.
I am trying to design an audio amplifier. I need to adjust the gain for both an output impedance of 8 ohms and 150 ohms.
The sound is mono. The signal at my input is 315mV rms and at the output 3.1V rms
I'm using the TPA6120A2DWPR IC (I'd love to get better alternative suggestions)
The component is suitable for working with the 2 types of output load.
Where in the calculations do I need to consider the load at the exit?
Thanks for the help!
