JAJSAR0B March 2007 – October 2017 LM95214
PRODUCTION DATA.
The SMBDAT output is an open-drain output and does not have internal pullups. A high level will not be observed on this pin until pullup current is provided by some external source, typically a pullup resistor. Choice of resistor value depends on many system factors but, in general, the pullup resistor must be as large as possible without effecting the SMBus desired data rate. This will minimize any internal temperature reading errors due to internal heating of the LM95214. The maximum resistance of the pullup to provide a 2.1-V high level, based on LM95214 specification for High Level Output Current with the supply voltage at 3 V, is 82 kΩ (5%) or 88.7 kΩ (1%).
