Hi,
I am total beginner with electronics....
I am learning this Daqarta scope program (www.daqarta) and at the moment I am wondering the power output of function generator. I am planning to buy (when I have the money) two velleman applifiers K4004B -
That should give me enough power. Problem is that manual says the outputs should be connected before power is applied. When testing things it is quite possible that I forget this. And it is quite possible I will short them for prolonged time. Velleman says that there is protection of
10s for shorts - that is not enough.Any way to solve these problems?
Then I would need a power supply for +/- 28 DC for these amplifiers. It is not clear to me what the maximum amperage should be - anyone? Where in the EU area to buy these? (I am also building my own power supply but I won't use it with anything valuable)
Now when waiting the money come to my way, I have discrete components and I would like to make simple amplifiers with just 1-4 transistor. I found some examples with Google but they had max input of 1 volt. My sound card gives out max 3V when maximum volume. Do anyone have a connection example for an amplifier which takes 0-3(5)V and gives out something like 0-6(10)V.
I have an idea of dividing the input voltage with resistors and test with different base-resistors - right?
