Hi Zack,
Is it possible for LTC4079 to have more wider temperature range from -35C to 80C? For most NTC thermistors from Vishay or TDK, about 0C ~ 40C range following below threshold.
In my application, I'd like to extend temperature range to -35C to 80C.

Hello,
Yes, you can use a thermistor with a lower beta value for less sensitivity to temperature. This will effectively extend the NTC range based on the fixed threshold ratios that the LTC4079 uses. These…
Hi Ma,
You're right about that. I've double-checked your calculations.
You may be able to get the NTC profile you need by adding series/parallel resistors. We typically add them like this:
The…
