INA128UAG4 Frequently Asked Questions (FAQ)
-
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 amplifier can be calculated using the formula: Gain = 1 + (R2/R1), where R1 and R2 are the external resistors connected to the gain pins.
-
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.
-
Yes, the INA128UAG4 can be used as a differential amplifier by connecting the inputs differentially and using the internal gain resistors.
-
The input impedance of the INA128UAG4 is typically around 10GΩ, making it suitable for high-impedance sources.
