INA122UA Frequently Asked Questions (FAQs)

  • The INA122UA can handle input voltages up to ±40V, but it's recommended to keep the input voltage within ±20V for optimal performance.
  • The INA122UA's common-mode voltage range is ±12V. Ensure that the input voltage is within this range by using voltage dividers or level-shifters if necessary.
  • The REF pin is a reference voltage input that allows you to set the output voltage of the INA122UA. You can connect it to a voltage reference or a resistive divider to set the output voltage to a specific level.
  • The gain of the INA122UA is determined by the ratio of the resistors Rg and Rf. The gain is calculated as Gain = (Rf / Rg) + 1. For example, if Rf = 1kΩ and Rg = 2kΩ, the gain would be (1kΩ / 2kΩ) + 1 = 1.5.
  • The null pins are used to adjust the offset voltage of the INA122UA. By connecting a potentiometer between the null pins and the output pin, you can adjust the output voltage to zero when the input voltage is zero.
