ADA2200 sine wave

Question asked by jul on Jun 7, 2018

I am using ADA2200. I need to excite my sensor with a sine wave. If I understand correctly, RCLK is only outputing a square wave. wich is very unpleasant because it is quiet tricky to  filtred out all the harmonics to obtain a pure sine wave, it can induce a phase shift and anyway I don't know how to design such bessel or butterworth filter.

 

Can I use the DAC of my microcontroler to excite my sensor with a sine and feed CLKIN with a TTL synchrone to the frequency sampling of the DAC ?
