INA199A2RSWR 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 ±20V to ensure accurate measurements.
• How do I calculate the gain of the INA199?
  The gain of the INA199 is fixed at 20V/V. You can calculate the output voltage by multiplying the input voltage by the gain.
• What is the purpose of the REF pin?
  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.
• Can I use the INA199 with a single-supply voltage?
  Yes, the INA199 can be used with a single-supply voltage. However, the output voltage range will be limited to 0V to VCC. You may need to add an offset voltage to the output to get a bipolar output.
• How do I reduce the noise in the output signal?
  To reduce noise, use a low-pass filter at the output, and ensure that the input signals are properly filtered and shielded. You can also use a capacitor between the REF pin and GND to filter out high-frequency noise.
