INA121U 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 for optimal performance.
  • The gain of the INA121U is set by the ratio of the resistors Rg and Rf. The gain can be calculated using the formula: Gain = (Rf / Rg) + 1.
  • The REF pin is used to set the output voltage reference point. It can be connected to a voltage reference or a fixed voltage source to set the output voltage range.
  • Yes, the INA121U can be used as a differential amplifier by connecting the input pins in a differential configuration. The output will be proportional to the difference between the two input signals.
  • The bandwidth of the INA121U is typically around 1.5 MHz, but it can be affected by the gain setting and the input impedance.
