AD586MNZ

Voltage Reference Overview

The AD586MNZ is a high-precision monolithic voltage reference manufactured by Analog Devices Inc. It provides a fixed 5.000 V output with an initial accuracy of ±2.0 mV and a maximum temperature coefficient of 2 ppm/°C over the 0°C to 70°C range. The device utilizes a proprietary buried Zener diode architecture, offering low noise performance with a typical value of 4 µV p-p in the 0.1 Hz to 10 Hz band. It features an industry-standard pinout, allowing for direct upgrades in existing systems. The AD586MNZ operates within a supply voltage range of 10.8 V to 36 V, consumes approximately 3 mA of quiescent current, and can source or sink up to 10 mA of output current.

Voltage Reference Feature Summary

• Laser trimmed for high initial accuracy and low temperature drift without external components
• Low noise generation utilizing a proprietary buried Zener diode design
• Includes a dedicated noise reduction pin for additional filtering via external capacitor
• Provides optional fine-trim capability for precise output voltage adjustment

Voltage Reference Applications

• Precision references for 8-, 10-, 12-, 14-, and 16-bit DACs
• Reference sources for successive approximation or integrating ADCs
• Multiplying CMOS DAC applications requiring stable reference voltages
• Stacked precision reference configurations for generating multiple voltage levels

Voltage Reference Procurement Notes

Verify that the specific order contains the 'NZ' suffix to confirm the component is lead-free compliant. Confirm the package type matches the required PCB footprint, as the AD586 series is available in PDIP, SOIC, and CERDIP variants. Ensure the selected grade meets the necessary temperature coefficient and accuracy specifications for the intended application environment before finalizing procurement.

Voltage Reference Selection Notes

Select the AD586MNZ when high precision and stability are required for analog signal processing. This model is suitable for applications demanding low drift over the industrial temperature range. Consider the optional trim pin if system calibration requires exact voltage alignment. Evaluate the need for the noise reduction pin if the application is sensitive to low-frequency noise, ensuring appropriate external capacitors are included in the design.

Voltage Reference Part Context

The AD586 represents a significant advancement in monolithic voltage reference technology, combining high precision with cost-effectiveness. It serves as a drop-in replacement for many standard 5 V references due to its industry-standard pinout. The device is widely used in data acquisition systems where accurate conversion relies on a stable reference voltage source.

Voltage Reference Replacement Considerations

Direct replacements include other grades within the AD586 family such as AD586KNZ or AD586LRZ, provided their accuracy and temperature coefficients meet the design requirements. Verify package compatibility when substituting between PDIP, SOIC, and CERDIP options.
