LTC1655CN8#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LTC1655CN8 involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing noise coupling between the analog and digital sections. A 4-layer PCB with a dedicated analog ground plane is recommended.
  • To ensure accurate temperature measurement, it's essential to calibrate the device, use a high-accuracy voltage reference, and minimize thermal gradients on the PCB. Additionally, using a thermocouple with a high sensitivity and a low thermal time constant can improve accuracy.
  • The maximum cable length for the LTC1655CN8's serial interface depends on the data rate and the quality of the cable. As a general guideline, a cable length of up to 10 meters is recommended for a data rate of 100 kHz. However, this can be extended to 30 meters or more with the use of a repeater or a high-quality, shielded cable.
  • To minimize EMI with the LTC1655CN8, use a shielded enclosure, keep the analog and digital sections separate, and use a common-mode choke or ferrite bead on the power supply lines. Additionally, use a low-pass filter on the analog input lines and ensure good PCB layout practices.
  • The recommended power-up sequence for the LTC1655CN8 is to first apply the analog power supply (VCC), followed by the digital power supply (VDD). This ensures that the analog circuitry is powered up before the digital circuitry, which helps to prevent latch-up and ensures proper device operation.
