INA139NA/250 Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the input pins is ±40V, but it's recommended to keep it within ±20V to ensure accurate measurements.
  • The gain of the amplifier is fixed at 100V/V. You can calculate the output voltage by multiplying the input voltage by the gain.
  • The bandwidth of the INA139NA/250 is 2.5 kHz, which means it can accurately measure signals up to 2.5 kHz.
  • No, the INA139NA/250 is not designed for high-current applications. The maximum output current is 10 mA, and it's recommended to keep the output current below 5 mA for accurate measurements.
  • To reduce noise and interference, use proper grounding, shielding, and layout techniques. Also, consider adding filters or capacitors to reduce electromagnetic interference (EMI).
