INA114AU/1K Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the INA114AU/1K can handle?
  The INA114AU/1K can handle input voltages up to ±40V, but it's recommended to keep the input voltage within ±20V for optimal performance.
• How do I ensure the INA114AU/1K is operating within its common-mode voltage range?
  The INA114AU/1K's common-mode voltage range is ±200mV. To ensure operation within this range, use a voltage reference or a resistive divider to set the input common-mode voltage to a value within this range.
• What is the purpose of the REF pin on the INA114AU/1K?
  The REF pin is used to set the output voltage of the INA114AU/1K. It can be connected to a voltage reference or a resistive divider to set the output voltage to a specific value.
• How do I calculate the gain of the INA114AU/1K?
  The gain of the INA114AU/1K is determined by the ratio of the resistors used in the feedback network. The gain can be calculated using the formula: Gain = (R2/R1) x (1 + Rg/Rf), where R1, R2, Rg, and Rf are the resistors used in the feedback network.
• What is the maximum output current that the INA114AU/1K can provide?
  The INA114AU/1K can provide an output current of up to ±20mA.
