Forum Post: RE: TMP441 Local/Remote Temperature Error

Hi Hidetoshi,

Thanks for using TI E2E Forums. In order to understand the cause of the differences between Local and Remote temperature I would need more information from the customer. An schematic showing the configuration of the TMP441 in the circuit with all the external components can help.

Is the customer following all the recommendations from the application section of the datasheet? i.e transistor connected between DXP and DXN; pull-up resistors in the I2C lines; power supply bypass capacitor.

Best Regards,
