SX8725
ZoomingADC for Pressure and Temperature Sensing
PCB Layout Considerations
PCB layout considerations to be taken when using the SX8725 are relatively simple to get the highest
performances out of the ZoomingADC. The most important to achieve good performances out the ZoomingADC
is to have a good voltage reference. The SX8725 has already an internal reference that is good enough to get
the best performances with a minimal amount of external components, but, in case an external reference is
needed this one must be as clean as possible in order to get the desired performance. Separating the digital
from the analog lines will be also a good choice to reduce the noise induced by the digital lines. It is also
advised to have separated ground planes for digital and analog signals with the shortest return path, as well as
making the power supply lines as wider as possible and to have good decoupling capacitors.
How to Evaluate
The SX8725 is a subset of the SX8724 thus for evaluation purposes the XE8000EV121 evaluation kit can be
ordered. This kit connects to any PC using a USB port. The “SX87xx Evaluation Tools” software gives the user
the ability to control the SX8724 registers as well as getting the raw data from the ZoomingADC and displaying
it on the “Graphical User interface”. For more information
