TMP121AIDBVT datasheet by Texas Instruments

TMP121AIDBVT Frequently Asked Questions (FAQs)

• What is the accuracy of the TMP121AIDBVT?
  The TMP121AIDBVT has an accuracy of ±1°C from -20°C to 70°C and ±2°C from -40°C to 125°C.
• How do I configure the TMP121AIDBVT for remote temperature sensing?
  The TMP121AIDBVT can be configured for remote temperature sensing by connecting the remote diode to the REXT pin and configuring the device for remote sensing mode through the I2C interface.
• What is the maximum cable length for remote temperature sensing?
  The maximum cable length for remote temperature sensing is 10 meters, but this can be extended up to 100 meters with the use of a repeater or a buffer.
• How do I handle thermal gradients when using the TMP121AIDBVT?
  To handle thermal gradients, ensure that the TMP121AIDBVT is mounted close to the thermal source, use thermal interface materials to reduce thermal resistance, and consider using a thermal shield or heat sink to reduce thermal gradients.
• What is the power consumption of the TMP121AIDBVT?
  The TMP121AIDBVT has a typical power consumption of 10 μA in shutdown mode and 200 μA in active mode.
