INA111AUE4 datasheet by Texas Instruments

INA111AUE4 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the INA111AUE4?
  The maximum power dissipation of the INA111AUE4 is 670mW at 25°C, but it can be derated to 560mW at 50°C and 450mW at 75°C.
• How do I layout the PCB to minimize noise and ensure optimal performance?
  To minimize noise and ensure optimal performance, it is recommended to use a 4-layer PCB with a solid ground plane, keep the input and output traces short and separate, and use a common-mode filter capacitor between the input pins.
• What is the recommended input impedance for the INA111AUE4?
  The recommended input impedance for the INA111AUE4 is 1kΩ to 10kΩ, but it can be as low as 100Ω or as high as 100kΩ depending on the specific application.
• Can I use the INA111AUE4 in a single-supply application?
  Yes, the INA111AUE4 can be used in a single-supply application, but it requires a voltage reference and a level-shifting circuit to ensure proper operation.
• How do I calculate the gain error and offset voltage of the INA111AUE4?
  The gain error and offset voltage of the INA111AUE4 can be calculated using the formulas provided in the datasheet, which take into account the input voltage, gain, and temperature.
