LM86
www.ti.com SNIS114E – DECEMBER 2001 – REVISED MARCH 2013 ±0.75°C Accurate, Remote Diode and Local Digital Temperature Sensor With Two-Wire
Interface
Check for Samples: LM86 FEATURES DESCRIPTION The LM86 is an 11-bit digital temperature sensor with
a 2-wire System Management Bus (SMBus) serial
interface. The LM86 accurately measures its own
temperature as well as the temperature of an external
device, such as processor thermal diode or diode
connected transistor such as the 2N3904. The
temperature of any ASIC can be accurately
determined using the LM86 as long as a dedicated
diode (semiconductor junction) is available on the
target die. The LM86 remote sensor accuracy of
В±0.75В°C is factory trimmed for the 1.008 typical
nonideality factor of the mobile Pentiumв„ў III thermal
diode. The LM86 has an Offset register to allow
measuring other diodes without requiring continuous
software
management.
