NTC configurations
I need to interface the [NTC thermistor](https://www.vishay.com/docs/29154/ntcle213e3.pdf) with the [SAM D5x/E5x](https://ww1.microchip.com/downloads/aemDocuments/documents/MCU32/ProductDocuments/DataSheets/SAM-D5x-E5x-Family-Data-Sheet-DS60001507.pdf) microcontroller.
During my research, I came across two common circuit configurations for NTC connections: one where the NTC is connected to VCC, and another where it is connected to GND. Please refer to the image below for reference.

[Image source-2](https://tavotech.com/accurate-temperature-measurement-using-an-ntc-thermistor-with-an-arduino-or-stm32-microcontroller/):

This NTC is a part of BMS which will be used for measuring the temperature of battery packs.

Could you advise on which configuration—NTC connected to VCC or to GND—is preferred for this application? Additionally, what criteria should be considered when deciding between the two options?

What guidelines should be followed to determine the appropriate ADC sampling rate for interfacing with an NTC thermistor in this context?

Is it recommended to place a parallel capacitor with the NTC thermistor? If so, what are the considerations for selecting the suitable capacitance value?
