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 INA169 is fixed at 50V/V. You can calculate the output voltage using the formula: Vout = (Vin x Gain) + Vref, where Vin is the input voltage and Vref is the reference voltage.
The REF pin is used to set the output voltage reference point. You can connect it to a voltage reference or a fixed voltage source to set the output voltage range. Typically, it's connected to a voltage divider or a voltage reference IC.
Yes, the INA169 can be used with a single supply voltage. However, the input common-mode voltage range is limited to VCC-2V to VCC+0.1V. You may need to add an external voltage divider or level shifter to adjust the input voltage range.
The bandwidth of the INA169 is 2.5MHz. It's suitable for most industrial and consumer applications, but may not be suitable for high-frequency applications.
