INA321EA/2K5 Frequently Asked Questions (FAQs)

  • The maximum power dissipation of INA321EA/2K5 is 670mW at 25°C. However, it's recommended to derate the power dissipation to ensure reliable operation.
  • To minimize noise and ensure optimal performance, it's recommended to follow good PCB layout practices such as separating analog and digital grounds, using a solid ground plane, and keeping the input and output traces short and symmetrical.
  • The recommended input impedance for INA321EA/2K5 is 1kΩ to 10kΩ. This ensures optimal common-mode rejection and noise performance.
  • Yes, INA321EA/2K5 can be used in a single-supply application. However, it's recommended to use a voltage divider or a reference voltage to set the input common-mode voltage to mid-supply.
  • The gain error and offset voltage of INA321EA/2K5 can be calculated using the formulas provided in the datasheet. The gain error is typically ±0.05% and the offset voltage is typically ±500μV.
