I am trying to build an amplification circuit to amplify signals generated from a function generator application by a smartphone so that the signal is powerfull enough say 10volts and 2A in such a way that the wave form doesn't change (a small change won't kill me though).I am still new to op-amps so bear with me please.
I read something about push pull transistor configuration to draw current to feed the powered signal. I will appreciate it if someone could suggest a proper circuit for my needs keeping in mind that the signal source is a smartphone which needs protection against voltages(currents) flowing to its audio jack.
Also, I would like to ask, If I used an audio amplifier circuit and injected the signal, would it work like that? If so, How can i protect my phone?
How would Darlington power transistors help me in this circuit (because I have them laying around).
Please bear with me and thanks in advance
