Sine wave generation

percy
on Apr 8, 2016

Can someone recommend a DAC to use for generating a 100Hz sine wave? Ideally I need 5 outputs that can each be programmed to 100Hz but with different phases and amplitudes. Thanks

    Hi Percy,

    If your goal is a plane sine wave, you might benefit from a DDS synthesizer. This avoids the need to generate your sine wave with a microcontroller or so. You could have a look at the AD9106, which has many options and 4 (differential) outputs. I know this doesn't match your 5-output-requirement, but maybe you can be smart and use a 180deg phase shift of one of the DAC outputs. Maybe there are other multi-channel DDS synthesizers available.

    Best regards, Max
