The LM95221 is a dual remote diode temperature sensor in
an 8-lead MSOP package. The 2-wire serial interface of the
LM95221 is compatible 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 programmed
to be 10-bits plus sign or 11-bits unsigned. In the
unsigned mode the LM95221 remote diode readings can
resolve temperatures above 127°C. Local temperature readings
have a resolution of 9-bits plus sign.
