INA223AIDSKR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VIN pin is 36V, but it's recommended to keep it below 30V for reliable operation.
  • To configure the INA223A for bidirectional current measurement, connect the SHUNT+ pin to the high-side of the shunt resistor and the SHUNT- pin to the low-side of the shunt resistor. Then, set the MODE pin to logic high to enable bidirectional measurement.
  • The RST pin is an active-low reset input that resets the INA223A to its default state. To use it, connect the RST pin to a logic low signal for at least 10ns to reset the device.
  • To calculate the current measurement, use the following formula: I = (VOUT x GAIN) / (RSHUNT x VFS), where I is the current, VOUT is the output voltage, GAIN is the gain setting, RSHUNT is the shunt resistor value, and VFS is the full-scale voltage.
  • For optimal performance, place the INA223A close to the shunt resistor and keep the traces short and wide. Use a ground plane under the device to reduce noise and ensure good thermal dissipation.
