    INA128U 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 INA128U is calculated by the ratio of the output voltage to the input voltage. The gain can be set by the external resistors Rg and Rf, according to the formula: Gain = (Rf/Rg) + 1.
    • 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 output voltage range.
    • To reduce noise and oscillations, use a low-pass filter at the input, keep the input and output traces short and away from noise sources, and use a capacitor between the REF pin and ground to filter the reference voltage.
    • The maximum output current of the INA128U is ±20mA, but it's recommended to keep it below ±10mA for optimal performance and to prevent overheating.
