AD640JNZ 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-grounding configuration to minimize noise and ensure that the analog and digital circuits are separated.
  • The AD640JNZ has an internal calibration circuit that is enabled by applying a voltage to the CAL pin. The calibration process is initiated by applying a voltage between 1.2V and 1.4V to the CAL pin. The device will then calibrate itself and store the calibration data in its internal registers.
  • The maximum input voltage that the AD640JNZ can handle is ±10V. Exceeding this voltage may damage the device. It's recommended to use input voltage limiting resistors or voltage clamping circuits to prevent overvoltage conditions.
  • To minimize noise and interference, use a low-pass filter at the input, keep the input traces short and away from digital signals, and use a shielded enclosure. Also, ensure that the power supply is well-regulated and decoupled with capacitors.
  • The recommended power-up sequence is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry.
