MAX9920ASA+T Frequently Asked Questions (FAQs)

  • A good PCB layout for the MAX9920ASA+T involves keeping the input traces as short as possible, using a solid ground plane, and placing the device close to the sensing resistor. Additionally, it's recommended to use a separate analog ground plane and to keep digital signals away from the analog signals.
  • The sensing resistor (Rs) value depends on the current range you want to measure and the desired output voltage range. A higher Rs value provides a larger output voltage swing, but also increases the power dissipation. A good starting point is to choose an Rs value that provides an output voltage range of 0.5V to 4.5V for the desired current range.
  • The MAX9920ASA+T has a specified temperature range of -40°C to +125°C. Over this range, the device's accuracy is affected by temperature. The device's gain and offset drift with temperature, which can affect the accuracy of the current measurement. However, the device's internal temperature compensation helps to minimize these effects.
  • The MAX9920ASA+T is designed to measure DC currents, but it can also be used to measure AC currents with some limitations. The device's bandwidth is limited to 100kHz, so it's suitable for measuring AC currents up to 100kHz. However, the device's accuracy may be affected by the AC current's frequency and amplitude.
  • Calibration involves adjusting the device's offset and gain to match the specific requirements of your application. This can be done by applying a known current to the device and adjusting the offset and gain to achieve the desired output voltage. The device's datasheet provides a calibration procedure that can be followed.
