ADR3625ARMZ - Analog Devices

ADR3625ARMZ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the ADR3625ARMZ?
  A good PCB layout for the ADR3625ARMZ 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.
• How do I ensure accurate voltage reference output from the ADR3625ARMZ?
  To ensure accurate voltage reference output, make sure to decouple the input pin (VIN) with a 10uF capacitor, use a low-ESR output capacitor (e.g., 10uF), and keep the output pin (VOUT) away from high-current or high-frequency signals.
• What is the maximum allowed voltage on the input pin (VIN) of the ADR3625ARMZ?
  The maximum allowed voltage on the input pin (VIN) of the ADR3625ARMZ is 12V, but it's recommended to keep it below 10V to ensure optimal performance and prevent damage to the device.
• Can I use the ADR3625ARMZ as a voltage regulator?
  No, the ADR3625ARMZ is a voltage reference device, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage. If you need a voltage regulator, consider using a separate device, such as the ADP3333 or ADP5050.
• How do I calculate the output voltage tolerance of the ADR3625ARMZ?
  The output voltage tolerance of the ADR3625ARMZ can be calculated by adding the initial accuracy (±0.1% at 25°C) to the temperature coefficient (±5ppm/°C) multiplied by the operating temperature range. For example, at 50°C, the output voltage tolerance would be ±0.2%.
