AD586BRZ-REEL7 概述
A voltage reference is a specialized type of voltage regulator whose primary function is to establish a stable, accurate reference voltage rather than efficiently convert power. Voltage references sit within the power-management and signal-conditioning hierarchy and are commonly used by ADCs, DACs, programmable amplifiers, sensors, and test equipment. The AD586’s 5 V output provides a useful reference level for systems requiring more stability than a general-purpose regulator can offer, particularly when converter accuracy or measurement traceability is important.
Key electrical features include a nominal 5 V output, ±0.05% initial accuracy, a 10 mA specified output-current capability, and low output noise. The manufacturer datasheet identifies the AD586 as a high-precision reference based on a buried Zener diode and laser wafer trimming. The AD586BRZ-REEL7 designation identifies the specified accuracy and temperature-grade family, while -REEL7 identifies the tape-and-reel ordering code. The package is an 8-pin SOIC, commonly designated 8-SOIC in distributor listings.
The AD586 is recommended for 8-, 10-, 12-, 14-, and 16-bit DACs requiring an external precision reference. It can also serve as the reference input for high-resolution ADCs, instrumentation amplifiers, and measurement systems. The reference’s output noise is typically 4 µV peak-to-peak according to the manufacturer datasheet. A noise-reduction pin allows an external capacitor to further reduce noise from the buried Zener diode, making the part useful when the system requires additional filtering.
Because the AD586 is a series reference, its supply input must remain above the output with sufficient headroom across temperature and load conditions. Designers should verify the input range, output-current demand, load capacitance, and bypass requirements against the manufacturer datasheet. Decoupling should be placed close to the supply and reference pins, and the noise-reduction capacitor should be selected with the required stability and settling behavior in mind.
This page combines verified manufacturer specifications, distributor package and pricing information, drop-in alternatives, comparison data, and practical design guidance for engineers evaluating the AD586BRZ-REEL7. It is intended to support component selection, reference design planning, and supply-chain review without replacing the manufacturer datasheet for final qualification.

典型应用
AD586BRZ-REEL7 适用于 6 应用s: Precision DAC Reference, High-Resolution ADC Signal Conditioning, Data-Acquisition Instrumentation, Industrial Process Control, Laboratory Test and Measurement, Precision Signal Conditioning.
Precision DAC Reference
The AD586BRZ-REEL7 is specifically suited to 8-, 10-, 12-, 14-, and 16-bit DACs that require an external precision reference. Its fixed 5.000 V output, ±0.05% verified initial accuracy, and laser-trimmed resistor network provide a stable reference level for converter calibration and signal generation. The 10 mA output-current capability is useful for moderate reference loads, while the noise-reduction pin can add filtering when the converter requires especially low reference noise. Place the reference close to the DAC reference pins, provide suitable supply decoupling, and verify the DAC’s required reference-input impedance and settling behavior.
推荐
High-Resolution ADC Signal Conditioning
Use the AD586BRZ-REEL7 as the external reference for high-resolution ADC front ends where reference stability directly affects conversion accuracy. A nominal 5 V output and ±0.05% initial tolerance help establish a defined full-scale reference for 8- to 16-bit systems, while the buried-Zener architecture and low typical noise of 4 µV peak-to-peak support stable measurements. The reference supply should be decoupled close to the IC, and the noise-reduction capacitor should be selected according to the manufacturer’s filtering guidance. Verify that the ADC reference input is compatible with the reference’s drive and noise behavior.
推荐
Data-Acquisition Instrumentation
The AD586BRZ-REEL7 fits precision data-acquisition systems requiring a stable analog reference for sensor conditioning, instrumentation amplifiers, and mixed-signal processing. Its fixed 5 V output provides a common reference for measurement chains, and the laser-trimmed network helps reduce initial calibration uncertainty. The device’s 10.8 V to 36 V input range supports regulated laboratory or industrial supplies when adequate headroom is maintained. Designers should account for reference noise, supply ripple sensitivity, startup behavior, and the external capacitor used on the noise-reduction pin. PCB placement should minimize coupling from switching nodes and digital return currents.
推荐
Industrial Process Control
The AD586BRZ-REEL7 can support industrial process-control modules that convert sensor signals into measurements or actuator commands. A precise 5 V reference improves the repeatability of ADC-based measurements and helps maintain predictable control-loop behavior across production units. The AD586’s series architecture requires a supply above the output, so the system should provide adequate input headroom and local bypass capacitance. The fixed reference also simplifies firmware calibration compared with a programmable reference, although production calibration may still be required when the system’s overall accuracy budget is tight. Verify temperature limits and long-term drift for the installed enclosure.
推荐
Laboratory Test and Measurement
The AD586BRZ-REEL7 is appropriate for laboratory instruments that require a repeatable 5 V reference for analog measurement or stimulus generation. Its laser-trimmed output and typical 4 µV peak-to-peak noise provide a useful starting point for low-noise analog systems, while the external noise-reduction pin allows additional filtering where required. Use stable, decoupled supply rails and keep the reference away from high-current switching paths to avoid reference modulation. The component’s 8-SOIC package is suitable for conventional surface-mount assembly, and its stated 10 mA capability should be checked against the instrument’s worst-case reference load.
推荐
Precision Signal Conditioning
The AD586BRZ-REEL7 can establish the reference rail for precision analog signal-conditioning circuits such as amplifiers, filters, and programmable gain stages. A stable 5 V reference helps control scaling and bias networks, while the low-noise buried-Zener design supports measurements where supply variation would otherwise appear as measurement error. The noise-reduction pin allows an external capacitor to reduce reference noise when the signal chain has sufficient bandwidth for the added settling time. Keep the reference return path close to the analog ground reference, observe the specified input range, and verify load current and capacitive loading before finalizing the schematic.

设计说明
Provide a regulated supply with sufficient headroom above the 5 V reference output across the full 10.8 V to 36 V input range and the required load. Place the supply bypass capacitor close to the AD586 supply pins and keep the high-current return path separate from sensitive reference returns. Because the AD586 is a series reference, inadequate input headroom can cause loss of regulation, increased output error, or unstable behavior.
Route the reference output and noise-reduction connection as short, quiet analog traces, with the external noise-reduction capacitor positioned close to the relevant AD586 pin. Keep switching nodes, high-current load paths, and digital clocks away from the reference network to reduce coupled noise. Use a continuous analog-ground reference where practical and verify the final layout by measuring output noise and load-transient response on the assembled board.
Do not treat the AD586 as a general-purpose 5 V power regulator or assume it can source unrestricted current. The verified capability is 10 mA, and the datasheet identifies a noise-reduction pin for optional filtering. Confirm the exact AD586BRZ grade, temperature limits, pinout, and capacitor recommendation before release. A substitute with the same 8-SOIC outline is not automatically equivalent unless its accuracy, drift, noise, input range, and reference topology are verified.
合规信息
The supplied verified data identifies the AD586 family and does not provide specific RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. The AD586 family datasheet mentions versions compliant with MIL-STD-883, but that does not establish the compliance status of AD586BRZ-REEL7. Confirm current manufacturer or distributor documentation before qualification.
