INA210AIDCKTG4 Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the input pins?
  The maximum voltage that can be applied to the input pins is ±40V, but it's recommended to keep it within the common-mode voltage range of ±26V to ensure accurate measurements.
• How do I calculate the gain error of the INA210?
  The gain error can be calculated using the formula: Gain Error (%) = (Vout / (Gain x Vin)) x 100, where Vout is the output voltage, Gain is the gain setting, and Vin is the input voltage.
• What is the purpose of the CAP pin, and how do I use it?
  The CAP pin is used to connect a capacitor to filter out high-frequency noise and improve the accuracy of the measurements. A 10nF to 100nF capacitor is recommended, and it should be connected between the CAP pin and the GND pin.
• Can I use the INA210 with a single-supply voltage?
  Yes, the INA210 can be used with a single-supply voltage, but the input common-mode voltage range will be limited to VCC - 2V to VCC + 0.1V. Additionally, the output voltage swing will be reduced, and the device may not be able to measure voltages near the supply rails.
• How do I ensure accurate measurements when using the INA210 with high-impedance sources?
  To ensure accurate measurements with high-impedance sources, it's recommended to use a buffer amplifier or a voltage follower to drive the input pins, and to keep the input impedance of the INA210 as low as possible by using a low-impedance input filter or a shielded cable.
