LM95221 Dual Remote Diode Digital Temperature Sensor with SMBus Interface May 2004 LM95221 Dual Remote Diode Digital Temperature Sensor with SMBus Interface General Description The LM95221 is a dual remote diode temperature sensor in an 8-lead MSOP package. The 2-wire serial interface of the LM95221 is patible with SMBus 2.0. The LM95221 can sense three temperature zones, it can measure the temperature of its own die as well as two diode connected transistors. The diode connected transistors can be a thermal diode as found in Pentium and AMD processors or can simply be a diode connected MMBT3904 transistor. The LM95221 resolution format for remote temperature readings can be...
