LM75BDP Frequently Asked Questions (FAQs)

  • The maximum cable length for the I2C bus depends on the system design and the capacitance of the bus. As a general rule, NXP recommends keeping the cable length as short as possible (less than 10 cm) to minimize signal degradation and ensure reliable communication.
  • During power-up, the LM75BDP may enter thermal shutdown if the die temperature is above the thermal shutdown threshold (TSD). To handle this, ensure that the power supply ramps up slowly (e.g., using a soft-start circuit) to allow the device to stabilize before the thermal shutdown threshold is reached.
  • No, the LM75BDP is designed to operate from a 2.7V to 5.5V power supply, but it is not recommended to use it with a 5V power supply. The device's internal voltage regulator is designed to operate at 3.3V, and using a 5V power supply may cause the device to malfunction or reduce its accuracy.
  • The LM75BDP does not require calibration. The device is factory-calibrated, and the temperature sensor is trimmed to provide an accuracy of ±2°C over the operating temperature range. However, if you need to improve the accuracy, you can use the offset register to adjust the temperature reading.
  • The LM75BDP can operate over a temperature range of -40°C to 125°C, but the accuracy of the temperature sensor is specified over a range of -20°C to 100°C. If you need to measure temperatures outside this range, you may need to use an external temperature sensor or a different device.
