datasheet - What are Normalized graphs?


I am reading this datasheet and there are some graphs that says (Normalized) on one of it's axis...what is this?



Answer



Normalization in the simplest case, means adjusting values measured on different scales to a notionally common scale, often prior to averaging.

In your case, the manufacturer is just showing you how Rds,on varies over temperature relative to its value at 25degC.


You should notice that y=1 for x=25. You can then infer that the resistance in the channel will increase 20% if the temperature rises to 100degC.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
