AD586TQ/883B

Voltage Reference Overview

The AD586TQ/883B is a high precision 5 V monolithic voltage reference utilizing an ion-implanted buried Zener diode and laser wafer trimming. It provides a fixed output of 5.000 V with an initial accuracy of ±2.5 mV and a maximum temperature coefficient of 10 ppm/°C over the −55°C to +125°C range. The device features low noise (100 nV/√Hz at 100 Hz) and includes a dedicated noise reduction pin for external filtering. It operates from an input voltage between 10.8 V and 36 V, draws 3 mA quiescent current, and supports sourcing or sinking up to 10 mA. The component is housed in an 8-pin ceramic dual in-line package (CDIP) compliant with MIL-STD-883.

Voltage Reference Feature Summary

• Laser trimmed for high initial accuracy and low temperature drift without external components
• Buried Zener topology ensures lower noise and drift compared to standard band gap references
• Includes optional fine-trim capability for precise output calibration
• MIL-STD-883 compliant construction suitable for demanding environments

Voltage Reference Applications

• Precision reference for 8-, 10-, 12-, 14-, or 16-bit DACs
• Reference source for successive approximation or integrating ADCs
• Multiplying CMOS DAC applications
• Stacked configurations for generating multiple precision voltages

Voltage Reference Procurement Notes

Verify that the specific ordering suffix corresponds to the required MIL-STD-883 screening level and grade. Confirm the package type matches the design requirements, as the AD586 family includes various options such as SOIC and PDIP. Ensure the selected grade meets the necessary temperature coefficient and initial accuracy specifications for the target application environment.

Voltage Reference Selection Notes

Select the AD586TQ/883B when full industrial temperature performance (-55°C to +125°C) and military-grade reliability are required. This model offers a balance of high precision (±2.5 mV) and robustness. Consider alternative grades like the AD586M if operation is limited to commercial temperatures, as they may offer tighter drift specifications within their narrower range.

Voltage Reference Part Context

The AD586 series represents a significant advancement in monolithic voltage reference technology by employing proprietary ion-implanted buried Zener diodes. Unlike standard band gap references, this architecture delivers superior noise performance and long-term stability. The device maintains an industry-standard pinout, facilitating direct upgrades in existing systems requiring precision 5 V references.

Voltage Reference Replacement Considerations

Direct replacements include other AD586 variants screened to MIL-STD-883 standards, such as the AD586SQ/883B. Verify that any substitute matches the 8-pin CDIP package and meets the specific electrical requirements for temperature coefficient and initial accuracy.
