Looking for a waveform generator IC

Hi

I`m looking for a  waveform generator IC, which I can simply set the waveform(sine, square, triangle), frequency, amplitude, then the IC can generate the waveform  what I set.

If  it`s a multi-channel IC, I hope the difference of phases of outputs can be set, too.

Could you give some suggestions?

I'd very much appreciate that.

thank.

  • ICL8038 or XR2206 would suit your requirement, but both are obsolete now!

    What frequencies and phases do you want to generate ? peak amplitude ?

    Thanks for the replying

    I'd like to generate the waveform with frequency of 100 to 400Hz, the peak amplitude is +5V to -5V, which Vpp is 10V.

    I think that`s a reachable spec.

    I was told the I should use the high speed DAC to implement it.

    But I won`t want to generate the voltage point by point.

    Thanks again

    How do you wish to control the frequency ? It seems a VCO circuit will suit your requirement.

    (voltage controlled oscillator ) Some wave shaping will be required for sine wave output.
