INA321E/2K5 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of INA321E/2K5?
  The maximum power dissipation of INA321E/2K5 is 670mW at 25°C. However, it's recommended to derate the power dissipation to ensure reliable operation.
• How do I layout the PCB to minimize noise and ensure optimal performance?
  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.
• What is the recommended input impedance for INA321E/2K5?
  The recommended input impedance for INA321E/2K5 is 1kΩ to 10kΩ. This ensures optimal common-mode rejection and noise performance.
• Can I use INA321E/2K5 in a single-supply configuration?
  Yes, INA321E/2K5 can be used in a single-supply configuration. However, the input common-mode voltage range is limited to VCC-1.5V to VCC+0.5V. Ensure that the input signal is within this range to maintain optimal performance.
• How do I calculate the gain of INA321E/2K5?
  The gain of INA321E/2K5 can be calculated using the formula: Gain = (Rf/Rg) x (1 + (Rb/Ra)). Rf, Rg, Rb, and Ra are the external resistors connected to the amplifier.
