INA219AID Frequently Asked Questions (FAQs)

  • The INA219 can measure bus voltages up to 36V, but the maximum voltage that can be applied to the VIN+ pin is 28V.
  • The INA219 has an internal calibration circuit that sets the full-scale range of the current measurement. No external calibration is required. However, the user can adjust the calibration register to fine-tune the current measurement range.
  • The INA219A is a newer version of the INA219 with improved specifications, such as higher accuracy and faster conversion time. The INA219A also has additional features like a programmable overcurrent alarm and a more precise voltage measurement.
  • The INA219 communicates with a microcontroller through an I2C interface. The SCL pin is the clock line, and the SDA pin is the data line. The microcontroller can read data from the INA219 by sending I2C commands to the device.
  • The INA219 has a typical operating current of 220 μA and a shutdown current of 5 μA. The power consumption depends on the operating mode and the frequency of the I2C interface.
