ADR421ARMZ-REEL7 Frequently Asked Questions (FAQs)

  • A good PCB layout for the ADR421 involves keeping the input and output traces separate, using a solid ground plane, and minimizing the distance between the device and the decoupling capacitors. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • To ensure proper decoupling, place a 10uF ceramic capacitor between the VIN pin and the GND pin, and a 0.1uF ceramic capacitor between the VOUT pin and the GND pin. These capacitors should be placed as close to the device as possible.
  • The maximum output current of the ADR421 is 10mA. Exceeding this current may cause the device to overheat or malfunction.
  • The output voltage of the ADR421 can be adjusted by connecting a resistor divider network between the VOUT pin and the ADJ pin. The output voltage can be calculated using the formula: VOUT = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
  • The ADR421 is rated for operation up to 125°C. However, the device's performance and accuracy may degrade at high temperatures. It's recommended to consult the datasheet and application notes for specific guidance on high-temperature operation.
