The maximum voltage that can be applied to the input pins is 80V, but it's recommended to keep it below 60V 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 by multiplying the input voltage by the gain. For example, if the input voltage is 1V, the output voltage would be 50V.
The CAP pin is used to connect a capacitor to filter out high-frequency noise and improve the stability of the device. A 10nF to 100nF capacitor is recommended.
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. Make sure to check the datasheet for specific voltage ranges.
To minimize noise and interference, keep the input traces as short as possible and away from noise sources. Use a ground plane and decouple the power supply with capacitors. Also, keep the output traces away from the input traces to prevent feedback.
