INA169NA/3KG4 datasheet by Texas Instruments

INA169NA/3KG4 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 for optimal performance.
• How do I calculate the gain of the INA169?
  The gain of the INA169 is fixed at 50V/V. You can calculate the output voltage using the formula: Vout = (Vin x Gain) + Vref, where Vin is the input voltage and Vref is the reference voltage.
• What is the purpose of the REF pin?
  The REF pin is used to set the output voltage reference point. You can connect it to a voltage reference or a voltage divider to set the output voltage range.
• Can I use the INA169 with a single supply voltage?
  Yes, the INA169 can be used with a single supply voltage. However, the input common-mode voltage range is limited to VCC-2V to VCC+0.5V. You may need to use a voltage divider or a level shifter to adjust the input voltage range.
• How do I reduce the noise and ripple in the output voltage?
  You can reduce the noise and ripple in the output voltage by adding a capacitor (e.g., 10nF) between the output pin and the GND pin. You can also use a low-pass filter or a voltage regulator to further reduce the noise.
