INA2128U/1K datasheet by Texas Instruments

INA2128U/1K Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the INA2128U/1K?
  The maximum power dissipation of the INA2128U/1K is 670mW at 25°C, but it can be derated to 560mW at 85°C.
• How do I optimize the layout for the INA2128U/1K to minimize noise and EMI?
  To minimize noise and EMI, use a 4-layer PCB with a solid ground plane, keep the input and output traces short and away from each other, and use a common-mode filter at the input.
• What is the recommended input impedance for the INA2128U/1K?
  The recommended input impedance for the INA2128U/1K is 1kΩ to 10kΩ to ensure optimal performance and minimize noise.
• Can I use the INA2128U/1K in a high-temperature environment?
  Yes, the INA2128U/1K can operate in a high-temperature environment up to 125°C, but the maximum junction temperature should not exceed 150°C.
• How do I calculate the gain error of the INA2128U/1K?
  The gain error of the INA2128U/1K can be calculated using the formula: Gain Error (%) = (Vout - (Vcm x Gain)) / (Vcm x Gain) x 100%, where Vout is the output voltage, Vcm is the common-mode voltage, and Gain is the gain setting.
