Key Differentiators
- MIL-STD-883 Class B compliance (vs Standard AD580)
- Hermetic TO-52-3 package (vs Plastic packages)
- Tight temperature coefficient of 10 ppm/Β°C (vs AD580SH/883B)
Design Notes
The AD580UH/883B requires an input voltage at least 2V above the output (2.5V) for proper regulation. For a 5V supply, ensure the input is stable and well-filtered. Use a 0.1uF ceramic capacitor on the input and a 1uF tantalum capacitor on the output to maintain stability and reduce noise.
The TO-52-3 metal can package provides good thermal conductivity. For high input voltages (e.g., 30V) and maximum output current (10mA), power dissipation is (30V-2.5V)*10mA = 275mW, which is within the package's capability. Ensure adequate airflow or heatsinking if operating near maximum ratings in high ambient temperatures.
Keep the AD580UH/883B close to the ADC reference input to minimize trace inductance and noise pickup. Use a ground plane and separate analog and digital grounds. Avoid routing high-frequency digital signals near the reference output. Follow the layout guidelines in the AD580 datasheet for optimal performance.
