SNAS207B May 2004 – January 2024 LM64
PRODUCTION DATA
In order to compensate for the errors introduced by non-ideality, the temperature sensor is calibrated for a particular processor. Texas Instruments temperature sensors are always calibrated to the typical non-ideality of a particular processor type.
The LM64 is calibrated for a MMBT3904 diode-connected transistor.
When a temperature sensor, calibrated for a specific type of processor is used with a different processor type or a given processor type has a non-ideality that strays form the typical value, errors are introduced.
Temperature errors associated with non-ideality may be introduced in a specific temperature range of concern through the use of the Temperature Offset Registers 11HEX and 12HEX.
The user is encouraged to send an e-mail to hardware.monitor.team@nsc.com to further request information on our recommended setting of the offset register for different processor types.
