Hey there,
i'm interested to use LTC2480. I also like to use his internal Temperature Sensor. But i can't find anything about the accuray of the internal temperature sensor. Can someone provide a Graph over Temperature and multiple LTC2480 to see how accurate the LTC2480 is?
Only thing i found in Datasheet is at Page 3 Internal PTAT Signal 390-450mV with typical Value of 420mV+-30mV. Gradient is 1.4mV/C... That means: 27°C +-21.4286°C isn't it?
Cheers!
Hi,
The internal PTAT has a typical value of 420mV at 27°C and is proportional to the absolute temperature value with a temperature coefficient of 420/(27 + 273) = 1.40mV/°C (SLOPE), as shown in the Figure below.
Regards,
Andrei
Cheers Andrei for your response. Do you know more about the temperature accuracy over Temperature? How accurate is the temperature measurement? I cant find details about that inside Datasheet...
For example a Plot like the above one...
