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 and to prevent damage to the device.
The gain of the amplifier can be calculated using the formula: Gain = (49.4kΩ / Rgain), where Rgain is the gain resistor value. The gain resistor value can be calculated using the formula: Rgain = (49.4kΩ / desired gain).
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. The REF pin should be decoupled with a capacitor to reduce noise and improve performance.
To reduce noise and oscillations, it's recommended to use a low-pass filter at the input, decouple the power supply and REF pin with capacitors, and use a ground plane to reduce electromagnetic interference (EMI).
The maximum current that the INA200AIDGKR can handle is ±50mA. Exceeding this current limit can cause damage to the device.
