The LM95010 is a digital output temperature sensor that has
single-wire interface compatible with National Semiconductor’s
SensorPath interface. It uses a ΔVbe analog temperature
sensing technique that generates a differential voltage
that is proportional to temperature. This voltage is digitized
using a Sigma-Delta analog-to-digital converter. The
LM95010 is part of a hardware monitor system, comprised of
two parts: the PC System Health Controller (Master), such
as a Super I/O, and up to seven slaves of which four can be
LM95010s. Using SensorPath, the LM95010 will be controlled
by the master and report to the master its own die
temperature. SensorPath data is pulse width encoded,
thereby allowing the LM95010 to be easily connected to
many general purpose micro-controllers.
