I want to output a 0~15V sin wave, so which amplifier can help me achieve this function?
There are many parts available. I need to know more about the request.
What is the supply voltage?
What is the output current demand?
Is there a sine wave input, or do you want to build an oscillator?
Is the output adjustable from 0V p-p to 15V p-p or are the sine peaks at 0V and 15V?

Thanks for your reply
There are two kind of supply voltage in my system, 5V and ±12V, and no special demand on output current.
I want to output an sin wave whos frequence can be adjusted from 0Hz to 100Hz, and the peaks can be adjusted from 0V p-p to 15V p-p.
In my present design:
1. Using DDS chip to generate the frequence adjusable sin wave
2. chose an sutiable amplifier to amplify the sin wave
as you see, the highest voltage in my system is 12v, if I want to output 15v sine wave, a dc/dc is requested,
I see you would like a +/-15V peak, which is 30V peak to peak. Is this correct?
How would you like to adjust the output amplitude, a potentiometer, or does the DSS chip control the amplitude?
Thank for your reply
Maybe my pool English leading your misunderstanding.
I want to ouput 15v peak to peak since wave, whose max value is 15v and min value is 0v.
In my present designing, I let DDS chip control the amplitude.
