The maximum voltage that can be applied to the input pins of the INA125PAG4 is ±40V, but it's recommended to keep the input voltage within the supply voltage range (±15V) to ensure accurate measurements.
The gain error of the INA125PAG4 can be calculated using the formula: Gain Error (%) = (Vout / (G x Vin)) x 100, where Vout is the output voltage, G is the gain, and Vin is the input voltage.
The REF pin on the INA125PAG4 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 INA125PAG4 can be used as a differential amplifier by connecting the inputs differentially and setting the gain accordingly. However, it's essential to ensure that the common-mode voltage is within the specified range.
To reduce noise and interference in your INA125PAG4 circuit, use proper layout techniques, such as separating analog and digital grounds, using shielding, and adding bypass capacitors. Additionally, consider using a low-pass filter or a noise-reducing amplifier configuration.
