Hi,
Good Day.
The customer is interested in using the TMP64-Q1 ±1% 47-kΩ Automotive Grade Linear Thermistor.
It is presented as a unipolar device, due to its silicon design.
His application might however require reversing the polarity to about -300 mV, and he would like to know exactly how the device will perform under reversed 300 mV polarization.
It would be great if he could obtain R(T) curves at -100 / -200 / and -300 mV on the TMP64-Q1.
He guesses the device includes some pn junctions that forbid reverse bias, but it should probably work fine under "mild" reverse conditions, and temperatures around ambient (max. 50°C in my case).
His application is related to kT/q compensation in analog log/exponential circuitry.
Please advise. Thank you very much.
Best Regards,
Ray Vincent
