INA139NA/250G4 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 the supply voltage range to ensure accurate measurements.
  • The gain of the INA139 is fixed at 5V/V, which means that the output voltage will be 5 times the input voltage difference between the IN+ and IN- pins.
  • The REF pin is used to set the output voltage reference point. It's typically connected to a voltage reference or a stable voltage source to set the output voltage offset.
  • Yes, the INA139 can be used with a single-supply voltage, but the input common-mode voltage range will be limited. It's recommended to use a dual-supply voltage for optimal performance.
  • To reduce noise and interference, use proper layout techniques, such as separating analog and digital grounds, using shielding, and adding bypass capacitors to the power supply pins. Additionally, consider using a low-pass filter or a ferrite bead to filter out high-frequency noise.
