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 INA200 is fixed at 20V/V, which means that the output voltage is 20 times the input voltage. You can use this gain to calculate the output voltage based on the input voltage.
The REF pin is used to set the reference voltage for the output. It's typically connected to a voltage reference or a voltage divider to set the output voltage range. The output voltage will be centered around the REF pin voltage.
Yes, the INA200 can be used with a single supply voltage. However, the input common-mode voltage range is limited to VCC - 1.5V to VCC + 0.5V, so you'll need to ensure that the input voltage is within this range.
The bandwidth of the INA200 is 50 kHz, which means it can accurately measure signals up to 50 kHz. However, the bandwidth can be affected by the gain setting and the input capacitance.
