AD580UH/883B Présentation
A voltage reference is a precision electronic circuit that produces a constant output voltage regardless of load current, input voltage, or temperature variations. It serves as a stable benchmark for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other precision analog circuits. Voltage references are fundamental building blocks in power management and signal conditioning, providing the accuracy required for high-resolution data conversion and measurement systems. The AD580UH/883B belongs to the family of series voltage references, which regulate output voltage by adjusting a series pass element, offering low output impedance and stable operation.
Key features of the AD580UH/883B include its laser-trimmed thin-film resistors, which achieve high initial accuracy of ±0.4%, and its excellent long-term stability of 25 V/month. The device operates with a low quiescent current, making it suitable for battery-powered and power-sensitive applications. Its wide input voltage range of 4.5 V to 30 V allows flexibility in various supply configurations, including operation from 5 V logic supplies. The TO-52-3 hermetic package ensures protection against moisture and environmental contaminants, enhancing reliability in harsh conditions.
Technically, the AD580UH/883B utilizes a bandgap reference architecture, which generates a stable voltage based on the bandgap energy of silicon. This design provides a temperature-compensated output that is largely independent of supply voltage variations. The device is laser-trimmed during manufacturing to achieve precise output voltage and temperature coefficient, ensuring consistent performance across production batches. The AD580UH/883B is recommended as a stable reference for all 8-, 10-, and 12-bit D/A converters that require an external reference, and its wide input range makes it ideal for digital panel meters and single-supply logic systems.
Typical applications include precision data acquisition systems, industrial process control, medical instrumentation, and military avionics. The AD580UH/883B is particularly suited for high-reliability environments where consistent voltage reference is critical. Its hermetic package and MIL-STD-883 compliance make it a preferred choice for defense and aerospace applications.
When designing with the AD580UH/883B, ensure adequate decoupling capacitors on the input and output to maintain stability. The device's low output impedance allows direct connection to ADC reference inputs, but proper layout practices should be followed to minimize noise pickup.

Notes de conception
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.
