Using DDS to generate a sine wave consisting of multiple frequencies???

Good day,

We looking at using the AD9835 DDS chip.

We need to generate a sine wave say at 300Hz but also need to superimpose two or more frequencies (say of about 3kHz, 4kHz etc) onto the 300Hz so that the resulting output contains sums and difference of signals.

Is this achievable using the AD9835 or which one is more appropriate?

 

Many thanks.
