Amp for signal generator
Amp for signal generator
(OP)
I wish to amplify sine wave from a signal generator 10Vpp 50 ohm load, 0.2 amp pp up to 1 amp pp for a test.
Running 0-10kHz.
Just like to build a simple circuit rather than buy expensive instrument. Might learn something.
thanks in advance

Or, if you choose to build, use one of those hybrid power opamps.

But you still have the 0 - 20 Hz gap.

I need to drive 1 amp total peak to peak. About 20 ohm.
thanks

The Bill Marsden circuit with 2N2222 and 2N2907 might be hard pressed to deliver the necessary power output.

The numbers we have seen so far indicate that the OP is a mechanical guy - which his handle also says.

Off-the-shelf audio amplifiers might be ideal in such cases. They're typically designed with good current driving capacity to keep the woofer cone under control.

Benta.

Can probably be found on eBay for an easy price.
