  • Wiki Page: Should I be concerned with layout if the converter is only 16-bit?

    Bob Benjamin
    FAQ: Should I be concerned with layout if the converter is only 16-bit? A: A great circuit design can be ruined with a poor layout. So even with a 12-bit system layout can be critical. Obviously with even higher resolution converters the layout becomes even more critical. One of the layout pitfalls...

  • Wiki Page: Where do I connect Analog and Digital grounds?

    Bob Benjamin
    FAQ: Where do I connect Analog and Digital grounds? A: Most all data converters require that the Analog (AGND) and Digital (DGND) ground be no more than 0.3V apart. This is generally shown in the Absolute Maximum specifications in the datasheet. To effectively achieve this requirement, there must...

  • Wiki Page: I don't need a ground plane do I?

    Bob Benjamin
    FAQ: I don't need a ground plane do I? A: A ground plane is best because it provides the lowest impedance for the return current path. Q: As long as the grounds are all connected, why does it matter? A: From a schematic point of view, all the grounds just connect to a symbol(s) and is basically...

  • Wiki Page: Which is better a single ground plane or a split ground plane?

    Bob Benjamin
    FAQ: Which is better a single ground plane or a split ground plane? A: This is rather difficult to answer. There are many viewpoints on this, so every PCB designer must consider the ramifications of using either of the grounding methods. In general, the single ground plane eliminates any possible...

  • Wiki Page: ADS8556 Ground Plane Question

    Tom Hendrick
    Original Question: ADS8556 Ground Plane Question Dear All: We will use ADS8556 , but we are confused in ground plane. Original top layer copper is a square without any gap. It is confused why lower layer AGND and BGND need a gap, because top layer entire square area connect to A, B GND by Via...
