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 INA197 can be calculated using the formula: Gain = 28.2 / (Rgain x Rload), where Rgain is the gain resistor and Rload is the load resistor. The gain resistor value can be chosen based on the desired gain and the load resistor value.
The CAP pin is used to connect a capacitor to ground, which helps to filter out high-frequency noise and improve the stability of the device. A 10nF to 100nF capacitor is recommended for this pin.
Yes, the INA197 can be used with a single supply voltage, but it's recommended to use a dual supply voltage for optimal performance. If a single supply voltage is used, the input common-mode voltage range will be limited, and the output voltage swing will be reduced.
To minimize noise and interference, it's recommended to follow good PCB layout practices, such as keeping the input and output traces separate, using a ground plane, and placing the device close to the input signal source. Additionally, it's recommended to use a shielded cable or twisted pair for the input signal connection.
