INA138NA/3K Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the INA138NA/3K is 670mW at 25°C, but it can be derated to 500mW at 70°C.
  • To ensure accuracy in high-temperature applications, it's essential to consider the temperature coefficient of the INA138NA/3K, which is 100ppm/°C. You can also use external components to compensate for temperature effects.
  • To minimize noise and interference, place the INA138NA/3K close to the signal source, use a ground plane, and keep the input traces short and shielded. Also, avoid running digital traces near the analog signal traces.
  • Yes, the INA138NA/3K can be used in a single-supply application, but you'll need to ensure that the input common-mode voltage is within the specified range (VCC-1.5V to VCC-0.5V). You may also need to add external components to level-shift the input signal.
  • The gain error of the INA138NA/3K can be calculated using the formula: Gain Error (%) = (Vout - (Gain x Vin)) / (Gain x Vin) x 100%. You can also use the datasheet's gain error vs. frequency graph to estimate the gain error.
