LM95221CIMM/NOPB datasheet by Texas Instruments

LM95221CIMM/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 4-layer PCB with a solid ground plane and thermal vias connecting the thermal pad to the ground plane is recommended for optimal thermal performance.
• How do I ensure accurate temperature measurements in high-noise environments?
  Use a low-pass filter or a shielded cable to minimize electromagnetic interference (EMI) and radio-frequency interference (RFI) effects on the temperature measurement.
• What is the maximum cable length for the digital interface?
  The maximum cable length for the digital interface is 10 meters (33 feet) to ensure reliable communication.
• Can I use the LM95221CIMM/NOPB in a hot-swap application?
  Yes, the LM95221CIMM/NOPB can be used in hot-swap applications, but ensure that the power supply is turned off before inserting or removing the device to prevent damage.
• How do I calibrate the temperature sensor for high-accuracy applications?
  Use a precision temperature reference source and a calibration routine to adjust the sensor's offset and gain to achieve high accuracy.
