INA118U/2K5 datasheet by Texas Instruments

INA118U/2K5 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the INA118U/2K5 can handle?
  The INA118U/2K5 can handle input voltages up to ±40V, but it's recommended to keep the input voltage within ±20V for optimal performance.
• How do I ensure the INA118U/2K5 is stable and doesn't oscillate?
  To ensure stability, make sure to decouple the power supply pins (V+ and V-) with 0.1uF capacitors, and use a 1uF capacitor between the output pin and the inverting input pin (IN-).
• What is the recommended layout and PCB design for the INA118U/2K5?
  Keep the input and output traces short and separate, use a ground plane, and avoid routing signals under the device. Also, place the decoupling capacitors close to the power pins.
• How do I calculate the gain of the INA118U/2K5?
  The gain of the INA118U/2K5 is determined by the ratio of the feedback resistors (Rf and Rg). Use the formula: Gain = (Rf / Rg) + 1.
• What is the maximum output current that the INA118U/2K5 can provide?
  The INA118U/2K5 can provide up to 20mA of output current, but it's recommended to keep the output current below 10mA for optimal performance.
