Hi,
You can use Ad9911, and use the test-tone modulation mode. It enables sinusoidal amplitude modulation on the carrier. The carrier is the Channel output in which the frequency can be set via registers. You can then set the register of aux Ch0 to set the magnitude of the modulating signal. You may refer to datasheet (test-tone mode section) for more info.
Hope this helps.
Best Regards,
