App note: Calibration of the ATtiny25/45/85 internal temperature reference

Here is an app note from Atmel describing how to calibrate the ATtiny internal temperature reference.

This application note describes how to calibrate and compensate the temperature measurements from the ATtiny25/45/85. It can also be used on other AVR microcontrollers with internal  temperature sensors. The temperature measurement is based on an on-chip temperature sensor that is coupled to a single ended ADC channel.
