INA117PG4 datasheet by Texas Instruments

INA117PG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the INA117PG4 can handle?
  The INA117PG4 can handle input voltages up to ±40V, but it's recommended to keep the input voltage within the supply voltage range (±15V) for optimal performance.
• How do I ensure accurate measurements with the INA117PG4?
  To ensure accurate measurements, make sure to follow proper layout and grounding techniques, use a low-noise power supply, and keep the input signals within the recommended range. Also, consider using a filter capacitor at the input to reduce noise and oscillations.
• What is the purpose of the REF pin on the INA117PG4?
  The REF pin is used to set the reference voltage for the amplifier. It can be connected to a voltage reference or a resistive divider to set the desired output voltage range. Leaving the REF pin unconnected will result in a default output voltage range of ±10V.
• Can I use the INA117PG4 as a differential amplifier?
  Yes, the INA117PG4 can be used as a differential amplifier by connecting the input signals to the IN+ and IN- pins. The amplifier will then amplify the difference between the two input signals.
• What is the output impedance of the INA117PG4?
  The output impedance of the INA117PG4 is typically around 1.5Ω, which is relatively low. This makes it suitable for driving low-impedance loads or long cables.
