Hi:

    I am using the AD5452 to  modulate the amplitude of 12 V p-p SINE signal and triangular wave.But it cause severe distortion when the frequency is 1MHz,triangular wave is even worse.It is described that the BW is 12MHz with the +-3.5V signal in datasheet.I guess that the BW is the reason of the distortion,am i right?

  And dose DAC have the term like the SR of OPAMP? Why does it have distortion when 1MHz?

 Do you have some DAC those are similar like AD5452 to recommend?

Thanks!
