ADM3491ARZ-1 Frequently Asked Questions (FAQ)
-
A good layout and routing practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the signal traces short and away from noise sources. Also, use a common mode choke or ferrite bead to filter the power supply lines.
-
Use a combination of ceramic and electrolytic capacitors to decouple the power supply lines. A 10uF ceramic capacitor and a 10uF electrolytic capacitor in parallel are recommended. Place the capacitors as close to the device as possible.
-
The maximum allowed voltage on the input pins is 5.5V, which is the absolute maximum rating. However, it's recommended to keep the input voltage within the specified operating range of 0 to 5V to ensure proper operation.
-
First, check the power supply voltage and ensure it's within the specified range. Then, verify the input signals and ensure they're within the specified range. Check the output load and ensure it's within the specified range. If the issue persists, check the device's temperature and ensure it's within the specified range.
-
The ADM3491ARZ-1 is rated for operation up to 125°C. However, the device's performance may degrade at high temperatures, and the output voltage may drop. Ensure proper heat sinking and thermal management to maintain a safe operating temperature.
