INA105AM Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the INA105AM?
  The maximum power dissipation of the INA105AM is 670mW at 25°C, but it can be derated to 560mW at 50°C and 450mW at 75°C.
• How do I ensure the accuracy of the INA105AM in high-temperature applications?
  To ensure accuracy in high-temperature applications, it's essential to consider the temperature coefficient of the INA105AM, which is typically ±0.05%/°C. You can also use external components to compensate for temperature effects or use a thermocouple to monitor the temperature.
• What is the recommended layout and grounding technique for the INA105AM?
  For optimal performance, use a star-grounding technique, where the analog and digital grounds are separated and connected at a single point. Keep the input and output traces short and away from noise sources, and use a ground plane to reduce electromagnetic interference (EMI).
• How do I handle electromagnetic interference (EMI) and radio-frequency interference (RFI) with the INA105AM?
  To minimize EMI and RFI, use a shielded enclosure, keep the INA105AM away from noise sources, and use a common-mode choke or ferrite beads on the input lines. You can also add a low-pass filter or a shielded cable to reduce noise.
• What is the recommended input impedance for the INA105AM?
  The recommended input impedance for the INA105AM is 1 kΩ to 10 kΩ. This ensures optimal common-mode rejection and minimizes the effects of input bias current.
