LM9061QDRQ1 datasheet by Texas Instruments

LM9061QDRQ1 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Texas Instruments recommends a thermal pad layout with a minimum of 2 oz copper thickness, and a thermal via array with a minimum of 10 vias under the package to ensure optimal thermal performance.
• How do I ensure the accuracy of the temperature measurement?
  To ensure accuracy, it's essential to calibrate the device, use a high-accuracy voltage reference, and minimize noise on the VCC and GND pins. Additionally, the device should be operated within the recommended temperature range and supply voltage.
• What is the maximum allowed voltage on the VCC pin?
  The maximum allowed voltage on the VCC pin is 5.5V. Exceeding this voltage may damage the device or affect its performance.
• Can I use the LM9061QDRQ1 in a high-vibration environment?
  Yes, the LM9061QDRQ1 is designed to operate in high-vibration environments. However, it's essential to ensure the device is properly soldered and the PCB is securely fastened to prevent mechanical stress.
• How do I handle the device's power-on reset (POR) during power-up?
  The POR circuitry ensures the device's outputs are in a high-impedance state during power-up. To handle POR, ensure a stable power supply, and add a capacitor to the VCC pin to filter out any noise or glitches.
