Hi,
I would like you to cofirm about below.
* Which schottky diode should be selected ?
According to datasheet of PGA280, there is following description.
VSN is connected to the substrate; therefore, the voltage at VSON or DGND must not turn on the substrate
diode to VSN. Use external Schottky diodes from VSON to VSN and from DGND to VSN (refer to Figure 50) to
prevent such a condition.
So, I believe user need to implement schottky diode. However, there is no description about required spec of this schottly diode.
How many current pulse(or continuous current) will cause ?
Or, if you have recommended schottky diode, could you please let me know ?
Best regards,
