Engineer It: When to Use an Analog Temp Sensor vs. a Thermistor

Learn how analog temperature sensors favorably compare with NTC thermistors when interfacing to an analog-to-digital converter. Well compare the output voltage to temperature curves for both devices, provide a supply current comparison, and explain the importance of output impedance.

Thermistors are a pain to use and writing code to make them linear is always a challenge.  The problem is that they are just so darn cheap, it's hard to justify not using a thermistor.

I do wonder how much extra it ends up costing to write that "challenging code" for a thermistor.
