LTC1690CMS8#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LTC1690CMS8 involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing the bypass capacitors close to the device. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended.
  • To ensure the accuracy of the temperature measurement, it is essential to calibrate the device, use a high-accuracy voltage reference, and minimize noise and thermal gradients on the PCB. Additionally, the device should be operated within its specified temperature range.
  • The maximum cable length for the remote sense lines depends on the specific application and the noise environment. As a general rule, the cable length should be kept as short as possible, and the lines should be twisted and shielded to minimize noise pickup. A maximum cable length of 10 inches (25 cm) is recommended.
  • To handle the inrush current during startup, a soft-start circuit can be used to limit the current surge. Additionally, the input capacitors should be chosen to handle the inrush current, and the device should be operated with a sufficient input voltage margin.
  • Input voltage ripple can affect the device's performance by introducing noise and reducing the accuracy of the temperature measurement. It is recommended to use a high-quality input filter or a low-dropout regulator to minimize the input voltage ripple.
