7.0 TEMPERATURE MEASUREMENT SYSTEM
The LM80 bandgap type temperature sensor and ADC per-
form 9-bit or a 12-bit two’s-complement conversions of the
temperature. An 8-bit digital comparator is also incorporated
that compares the readings to the user-programmable Hot
and Overtemperature setpoints, and Hysteresis values.
7.1 Temperature Data Format
Temperature data can be read from the Temperature, T
