LTC2983ILX#PBF: t-couple temperature measurement, cold junction channel diode, how to determine the ideal factor of cold junction diode?
Hi Jack Song,
Please take a look at my answer to this related question:
As for ltc2983, I have found a problem in the past few days, which is about the compensation of cold junction
The t-couple measurement is quite obvious. There is a cold junction compensation diode on the circuit board. If the ambient temperature of the earphone tube rises, the t-couple temperature actually measured will also rise. Is this my wrong usage?
