ADR381ARTZ-R2 Frequently Asked Questions (FAQ)
-
A good PCB layout for the ADR381ARTZ-R2 involves keeping the device away from high-current carrying traces, using a solid ground plane, and minimizing the distance between the device and the output capacitor. A 4-layer PCB with a dedicated analog ground plane is recommended.
-
To ensure accurate voltage output over temperature, it's essential to follow proper PCB layout guidelines, use a high-quality output capacitor, and consider using a temperature compensation circuit. Additionally, calibrate the system at multiple temperatures to account for any temperature-related drift.
-
A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for the output capacitor. This value provides a good balance between noise filtering and stability. Avoid using electrolytic capacitors as they can introduce additional noise and affect the device's performance.
-
To minimize noise and ripple, use a low-ESR output capacitor, keep the device away from noisy power supplies, and consider adding a noise-reducing filter circuit. Additionally, ensure the device is properly decoupled from the power supply using a 10uF to 100nF capacitor.
-
The maximum allowed input voltage for the ADR381ARTZ-R2 is 15V. Exceeding this voltage can cause permanent damage to the device. Ensure the input voltage is within the recommended range to maintain device reliability and performance.
