INA2133UA datasheet by Texas Instruments

INA2133UA Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the input pins?
  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.
• How do I calculate the gain of the amplifier?
  The gain of the amplifier can be calculated using the formula: Gain = (R2/R1) x (1 + (Rgain/Rf)). R1, R2, Rgain, and Rf are the resistors connected to the amplifier.
• What is the purpose of the REF pin?
  The REF pin is used to set the reference voltage for the amplifier. It can be connected to a voltage source or left open-circuit, depending on the application.
• Can I use the INA2133UA as a single-ended amplifier?
  Yes, the INA2133UA can be used as a single-ended amplifier by connecting the negative input to ground and using the positive input as the signal input.
• What is the maximum current that the output can source?
  The maximum current that the output can source is ±20mA, but it's recommended to keep it within ±10mA for optimal performance.
