Other Parts Discussed in Thread: LM57, LM94022, UCD74120
We would like to use the LM57-10 to measure the board temperature of our UCD9246 based design. This will be fed directly into the "TEMPERATURE" pin, w/o a mux.
Fusion Digital Power Design (FDPD) allows one to define a temperature sensor, and when I flip the "sensitivity" around in order to get sensor "gain" I end up with this selection window.
I guess it doesn't automatically calculate the voltage at 0C (2.202V)? Nor a sensitivity value? I just want to make sure I put this in correctly.
BTW, the LM57 has 4 different sensitivity curves, we're using J4 -> -10.339 mV/deg C, so it should be somewhat close to included LM94022.
Thanks, Best, Steve
