#171844 - what is conclusion for OP? Responding to: ???'s previous message |
- is needed additional hardware ? (sample-hold, zero crossing?, otr both?).
In this( and any) case - 3 fixed freq , fixed waveform (sinewave) - problem is to select proper chips to make things. I'm still in doubt that this Aduc is matching part. If high precision is needed - expensive S/H will be needed. And this comes from selected Aduc -which is expensive too, and probably is aimed for different applications - high resolution sensors i think. regards |
