INA2191A3IYBJR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VIN pin is 26V, but it's recommended to keep it below 25.5V to ensure accurate measurements.
  • Calibration is not required for the INA2191, as it has an internal calibration circuit that sets the gain and offset of the current measurement. However, you can adjust the calibration register (CAL) to fine-tune the gain and offset if needed.
  • The RSHUNT resistor is used to sense the current flowing through the load. Choose a value that is low enough to minimize voltage drop but high enough to provide accurate current measurements. A typical value is 0.1 ohms to 0.01 ohms.
  • No, the INA2191 is designed to measure DC currents only. It's not suitable for measuring AC currents due to its internal filtering and averaging circuits.
  • The INA2191 has an overcurrent detection feature that can be enabled by setting the OVF (overcurrent flag) bit in the configuration register. When an overcurrent condition is detected, the INA2191 will set the OVF bit and optionally trigger an interrupt.
