This gives a better curve fit.
No, but I'll try that Eric. The emitter degeneration resistor is intended to minimise any temperature drift contribution from the transistor while not dropping too much voltage. I'm sure there's some drift, but do you see any way round using diodes (the main cause of drift) to get a non-linear response whether using my transistor circuit or your op-amp circuit? But considering either circuit will be used with a small gauge marked vaguely 0,50,100% I doubt the drift would be objectionable.
That was a rash statement! Have to think of some way of compensating, since 50C is quite likely under a dashboard. Thermistor across R3 perhaps? Do you know if there's a thermistor model for LTS?I doubt the drift would be objectionable
Yes, just done the check too.
