DESCRIPTION
The LM95241 is a precision dual remote diode
temperature sensor (RDTS) that uses TI's TruTherm
technology. The 2-wire serial interface of the
LM95241 is compatible with SMBus 2.0. The
LM95241 can sense three temperature zones, it can
measure the temperature of its own die as well as
two diode connected transistors. The LM95241
includes digital filtering and an advanced input stage
that includes analog filtering and TruTherm
technology that reduces processor-to-processor non-
ideality spread. The diode connected transistors can
be a “thermal diode” as found in Intel and AMD
processors or can simply be a diode connected
MMBT3904 transistor. TruTherm technology allows
accurate measurement of “thermal diodes” found on
small geometry processes such as 90nm and 65nm.
The LM95241 supports user selectable thermal diode
non-ideality of either Intel processor on 90nm or
65nm process or 2N3904.
