TMP141AIDBVT datasheet by Texas Instruments

TMP141AIDBVT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the TMP141AIDBVT?
  The TMP141AIDBVT can operate from -40°C to 125°C, but the accuracy of the temperature measurement is specified from -20°C to 100°C.
• How do I configure the TMP141AIDBVT for remote temperature sensing?
  The TMP141AIDBVT can be configured for remote temperature sensing by connecting the internal diode to an external diode or thermistor. The internal diode is connected to pins 1 and 2, and the external diode or thermistor is connected to pins 3 and 4. The device can then be configured to measure the temperature of the external diode or thermistor using the TCR (Thermistor Characteristic Resistance) or VBE (Base-Emitter Voltage) modes.
• What is the typical current consumption of the TMP141AIDBVT?
  The typical current consumption of the TMP141AIDBVT is 120 μA, but it can be as low as 60 μA in shutdown mode.
• How do I interface the TMP141AIDBVT with a microcontroller?
  The TMP141AIDBVT can be interfaced with a microcontroller using the I2C or SMBus interface. The device has a 7-bit address, and the microcontroller can read the temperature data from the device using the I2C or SMBus protocol.
• What is the accuracy of the temperature measurement of the TMP141AIDBVT?
  The accuracy of the temperature measurement of the TMP141AIDBVT is ±1°C from -20°C to 100°C, and ±2°C from -40°C to 125°C.
