TLA2021IRUGT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a star topology for the power supply and keep the analog and digital power supplies separate.
  • Use a high-impedance buffer amplifier to drive the input pins, and ensure the input voltage is within the specified range. Also, use a low-noise, low-impedance power supply to minimize noise and voltage drops.
  • The maximum input voltage is 6.5V, but it's recommended to keep it below 5.5V to ensure accurate measurements and prevent damage to the device.
  • Perform a system calibration by applying a known input voltage and adjusting the gain and offset registers to achieve the desired accuracy. Use the internal calibration registers to trim the gain and offset errors.
  • The recommended clock frequency is between 1 MHz and 4 MHz. A higher clock frequency can improve the conversion rate, but it may also increase power consumption and noise.
