INA326EA/250 datasheet by Texas Instruments

INA326EA/250 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the INA326EA/250?
  The maximum power dissipation of the INA326EA/250 is 670mW at 25°C, but it can be derated to 500mW at 85°C.
• How do I optimize the layout for the INA326EA/250 to minimize noise and EMI?
  To minimize noise and EMI, keep the input traces as short as possible, use a ground plane, and place the device close to the signal source. Also, use a low-ESR capacitor for decoupling and keep the power supply traces away from the signal traces.
• What is the recommended input impedance for the INA326EA/250?
  The recommended input impedance for the INA326EA/250 is 1kΩ to 10kΩ. This ensures optimal performance and minimizes noise.
• Can I use the INA326EA/250 for high-temperature applications?
  Yes, the INA326EA/250 is rated for operation up to 125°C, but the maximum junction temperature is 150°C. However, the device's performance may degrade at high temperatures, so it's essential to consider thermal management and derating.
• How do I calculate the gain error of the INA326EA/250?
  The gain error of the INA326EA/250 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.
