INA2126U datasheet by Texas Instruments

INA2126U 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 to ensure accurate measurements.
• 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 + (R4/R3)), where R1, R2, R3, and R4 are the external 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 reference or a resistive divider to set the desired reference voltage.
• How do I reduce noise and interference in my circuit?
  To reduce noise and interference, use proper PCB layout techniques, such as separating analog and digital grounds, using shielding, and adding bypass capacitors to the power supply lines.
• What is the maximum current that the output can drive?
  The maximum current that the output can drive is ±20mA, but it's recommended to keep it within ±10mA to ensure stable operation.
