The ADT74811 is a 3-channel digital thermometer and under/ over temperature alarm, intended for use in PCs and thermal management systems. It can measure its own ambient temperature or the temperature of two remote thermal diodes. These thermal diodes can be located in a CPU or GPU, or they can be discrete diode connected transistors. The ambient temperature, or the temperature of the remote thermal diode, can be accurately measured to 1C. The temperature measurement range defaults to 0C to +127C, compatible with ADM1032, but can be switched to a wider measurement range from -64C to +191C.
