LOG112AIDR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other to minimize noise coupling.
  • The LOG112AIDR requires a bias voltage of 2.5V to 5.5V. Ensure the bias voltage is stable and noise-free, and that the input signal is within the recommended common-mode voltage range.
  • The LOG112AIDR can handle input signal amplitudes up to 5Vpp. Exceeding this limit may result in distortion and reduced accuracy.
  • Temperature compensation can be achieved by using a temperature sensor and adjusting the bias voltage accordingly. Alternatively, use a temperature-compensated voltage reference to minimize temperature-related errors.
  • The recommended input impedance is 1kΩ to 10kΩ. Higher input impedance may result in reduced accuracy and increased noise sensitivity.
