LOG112AID Frequently Asked Questions (FAQ)

  • 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 LOG112AID requires a bias voltage of 2.5V to 5.5V. Ensure the bias voltage is stable and noise-free, and that the input voltage is within the recommended range.

  • The LOG112AID 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.

  • The LOG112AID is suitable for high-frequency applications up to 100 MHz. However, ensure proper PCB layout and decoupling to minimize noise and ringing.
