ATM90E32AS-AU-R Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a star topology for the power supply and keep the high-frequency components away from the analog circuitry.
  • Calibration involves adjusting the gain and offset of the current and voltage channels. Use the built-in calibration registers to adjust the gain and offset. You can also use the internal calibration source to calibrate the device. Refer to the application note AN200043 for detailed calibration procedures.
  • The maximum frequency of the pulse output is 100 kHz. However, the recommended frequency is 10 kHz to 50 kHz for most applications.
  • Yes, the ATM90E32AS-AU-R can be used for polyphase energy metering applications. You can connect multiple devices in a master-slave configuration to measure energy in polyphase systems.
  • To ensure EMC, use a metal shield around the device, keep the analog and digital circuits separate, and use a common mode choke to filter the power supply. Also, follow the recommended PCB layout and use a shielded cable for the current sensor.
