ADR423ARZ Frequently Asked Questions (FAQs)

  • A good PCB layout for the ADR423ARZ involves keeping the input and output traces separate, using a solid ground plane, and placing the device close to the analog signal source. Additionally, using a 4-layer PCB with a dedicated power plane and a dedicated ground plane can help reduce noise and improve performance.
  • To ensure proper biasing, connect the VREF pin to a quiet, low-impedance voltage source, such as a voltage regulator or a battery. The VREF pin should be decoupled with a 10uF capacitor to reduce noise. Additionally, ensure that the input voltage is within the recommended range of 2.7V to 5.5V.
  • The recommended input impedance for the ADR423ARZ is less than 1kΩ to ensure accurate voltage measurement. Higher input impedance can lead to measurement errors due to voltage divider effects.
  • To protect the ADR423ARZ from overvoltage and ESD damage, use a voltage clamp or a transient voltage suppressor (TVS) diode on the input pins. Additionally, use a series resistor and a capacitor to filter out high-frequency noise and transients.
  • The recommended calibration procedure for the ADR423ARZ involves applying a known voltage source to the input pins and adjusting the internal gain and offset registers to achieve accurate voltage measurement. The calibration procedure should be performed at multiple temperatures and voltage levels to ensure accuracy across the operating range.
