Hi,

I am new to this and request you to help me with one ckt.

I need a ckt using XR2206 to run a load of about 10 to 20watts max @ 15V max with input from a 12Volts source. The output be with 10Hz to 600Hz (variable) and with different wave forms of sine, square, saw tooth (selectable).

Thanks and regards,

Kumar

 

There was a general purpose amp posted a month or two ago ... can take a look for it.
Here is the circuit ... edfet buffer:
.... this will have to be modified, but might serve as a starting point for your design requirements.

Here is an LtSpice run:

 

OH, Thanks very much for the suggestion. Will look into it. Thanks once again.

... do you have + and - minus sine wave, or just + ... ?

Xr2206 uses a positive 10 to 26V and ground supply. Output is a sine wave riding a DC bias. The bias can be adjusted as needed (see DATASHEET for details).
