Anything from Texas is the best.Ugh...I did some googling and I can't decide between these...I've never used any and I don't know which one is the best
OPA627
TL072
AD8610
AD829
AD8033
OPA2134
You can always flip a coin.Thanks nsaspook
Ah damnit...see the thing is, the other opamp you showed me was titled "High Definition Audio OpAmp" while this one is named "Precision High Speed" opamp...now I'm in the same dilemna again...do I pick the audio opamp or the best spec one?
With a single polarity supply the non-inverting input of the opamp is biased at half the supply voltage which makes its output at half the supply voltage so it can swing equally up and down. Then the output of the class-AB output stage is also at half the supply voltage. If you connect a speaker directly to the output and to ground then it will pass a high DC current all the time which pulls the speaker cone to one side and heats the speaker and the upper output transistor.I don't understand the coupling capacitor part...where do I put my speaker? Plus, this opamp stage is only my voltage gain stage...the output of this opamp is going to a class AB amplifier, so do I place the output of the class AB amplifier in parallel with a capacitor??
