ADR443ARZ Frequently Asked Questions (FAQs)

  • A good PCB layout for the ADR443ARZ involves keeping the input and output traces short and separate, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated analog ground plane is recommended.
  • To ensure stability, make sure to follow the recommended capacitor values and placement, keep the input and output impedance matched, and avoid capacitive loading on the output. Also, ensure the device is operated within its specified voltage and temperature ranges.
  • The maximum power dissipation of the ADR443ARZ is 1.4W. However, it's recommended to derate the power dissipation based on the ambient temperature and desired reliability. A good rule of thumb is to keep the junction temperature below 125°C.
  • Yes, the ADR443ARZ can be used as a voltage reference for an ADC. However, it's essential to consider the noise and drift specifications of the ADR443ARZ and ensure they meet the requirements of your ADC application.
  • The output voltage of the ADR443ARZ is determined by the internal bandgap voltage (1.2V) and the external resistor divider network. Use the formula: Vout = 1.2V x (R1 + R2) / R2, where R1 and R2 are the external resistors.
