So figure 2 for my application would be a better choice, and how much power dose figure 2 have then figure 16.Whats the maximum gain for this amp is it a gain of 39 or higher using figure 2 or figure 16. I want to have a variable gain so I could go from the lowest to the highest gain for maximum amplification. Or is this amp sets to a gain of 39.
What i want to do is add a plug to the inputs of the amp if i want a two channel stereo amp then with a two way switch added so i could switch from the plug or the single coming from the Mics Preaamp, but also feed the Mics Preamp output to the amps input.
Then on the output of the amp has the headphone jack and the optional speaker (like on the LM386) then the single from the output of the amp gos to the decoder.
How would i do this and which pins in figure 2 would connect to the plug for stereo and feed the Mics preamp single to the inputs of the amp. I might need to maybe use figure 1, and isn't figure 1 the same as figure 16. If this all makes sense.
Because figure 2 is mono not stereo correct!
Which circuit would give the power, stereo. and a variable gain. I stuck on the amp.
