INA169NA/3K datasheet by Texas Instruments

INA169NA/3K 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 and to prevent damage to the device.
• 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 fixed voltage source to set the output voltage range. Typically, it's connected to a voltage divider or a voltage reference IC.
• 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+0.1V. You may need to add an external voltage divider or level shifter to adjust the input voltage range.
• What is the bandwidth of the INA169?
  The bandwidth of the INA169 is 2.5MHz. It's suitable for most industrial and consumer applications, but may not be suitable for high-frequency applications.
