LOG101AID datasheet by Texas Instruments

LOG101AID Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the LOG101AID?
  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 noise sources. Use a common mode choke or a ferrite bead to filter the input power.
• How do I ensure the LOG101AID is properly biased for optimal performance?
  The LOG101AID requires a bias voltage of 2.5V to 5.5V. Ensure the bias voltage is stable and noise-free. A decoupling capacitor of 10uF or higher is recommended to filter the bias voltage.
• What is the maximum input voltage that the LOG101AID can handle?
  The LOG101AID can handle input voltages up to 12V, but the recommended maximum input voltage is 10V to ensure optimal performance and prevent damage to the device.
• How do I compensate for temperature effects on the LOG101AID?
  The LOG101AID has a temperature coefficient of 0.01%/°C. To compensate for temperature effects, use a temperature sensor and adjust the bias voltage accordingly. Alternatively, use a temperature-compensated voltage reference.
• What is the recommended input impedance for the LOG101AID?
  The recommended input impedance for the LOG101AID is 1kΩ to 10kΩ. A higher input impedance can lead to reduced accuracy and increased noise sensitivity.
