Product details
Overview
AD586LR-REEL from Analog Devices is a precision 5.000 V monolithic voltage reference IC based on a buried Zener diode architecture, delivering ±2.5 mV initial accuracy, 5 ppm/°C max temperature coefficient over 0°C to 70°C, and 100 nV/√Hz spectral noise density. It sources or sinks up to 10 mA and features dedicated noise reduction (Pin 8) and output trim (Pin 5) terminals for system-level calibration in high-resolution data converters.
For engineers reviewing the AD586LR-REEL datasheet, AD586LR-REEL pinout, AD586LR-REEL application, or AD586LR-REEL equivalent, this page delivers verified specifications, SOIC-8 package mapping, functional pin roles, real-world converter interface use cases, and two validated alternative references with documented performance trade-offs.
Technical Context
The AD586LR-REEL implements a proprietary ion-implanted buried Zener reference core with laser-trimmed thin-film resistors, enabling lower drift and noise than bandgap alternatives. Its internal buffer amplifier provides robust load regulation and transient response for driving ADC/DAC reference inputs.
It supports optional external fine-trim via Pin 5 (TRIM) and noise filtering via Pin 8 (NOISE REDUCTION) with a 1 µF capacitor to ground, reducing broadband noise to ~160 µV p-p. The device operates from 10.8 V to 36 V input and maintains specified performance across 0°C to 70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±2.5 mV at 25°C - enables direct replacement of legacy 5 V references without recalibration in 12-bit systems. |
| Tempco | 5 ppm/°C max (0°C to 70°C) - ensures ≤0.35 mV total drift over industrial ambient range, critical for stable DAC/ADC gain. |
| Noise Density | 100 nV/√Hz at 100 Hz - limits RMS noise contribution to <1.6 µV in 250 kHz bandwidth, preserving ENOB in 14-bit+ converters. |
| Load Drive | ±10 mA sourcing/sinking - supports direct drive of multiple converter reference inputs or op-amp bias networks. |
| Line Regulation | ±100 µV/V (10.8–36 V) - rejects supply ripple without external regulators, simplifying power domain design. |
| Long-Term Stability | 15 ppm/1000 hr - guarantees minimal calibration drift in metrology or medical instrumentation over 1-year deployment. |
| Quiescent Current | 2–3 mA - enables low-power operation in battery-backed precision systems while maintaining full performance. |
Pinout & Package
AD586LR-REEL is supplied in an 8-lead SOIC package (R-8, JEDEC MS-012AA), 5.00 mm × 4.00 mm body, 1.27 mm lead pitch, with gull-wing leads and 0.10 mm coplanarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | TP1 (Factory Test Point) | No connection required; dummy pad only - must remain unconnected to avoid calibration shift or damage. |
| 2 | VIN | Main power input (10.8–36 V); supplies buried Zener and buffer amplifier - requires local 0.1 µF decoupling. |
| 3 | TP1 (Factory Test Point) | No connection required; dummy pad only - not electrically accessible in final circuit. |
| 4 | GND | Analog ground reference for Zener core and output stage - must tie to clean system AGND plane. |
| 5 | TRIM | Fine-adjust node for ±6% output scaling; connects to external resistor divider to calibrate to exact 5.000 V or binary values (e.g., 5.12 V). |
| 6 | VOUT | Regulated 5.000 V output; capable of sourcing/sinking 10 mA - directly interfaces ADC REF pins or DAC VREF inputs. |
| 7 | TP1 (Factory Test Point) | No connection required; dummy pad only - no signal or power function in application circuit. |
| 8 | NOISE REDUCTION | Filter node for external 1 µF capacitor to GND; reduces 0.1–1 MHz noise by ~25%, critical for low-noise SAR ADCs. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed accuracy & tempco | Eliminates need for external trimming components and post-assembly calibration in production test flows. |
| Buried Zener topology | Delivers 2× lower drift and 3× lower 1/f noise vs. bandgap references, enabling higher DC stability in precision measurement. |
| Noise reduction pin (Pin 8) | Enables configurable 12 Hz low-pass filtering of Zener noise without modifying core reference architecture. |
| Output trim capability (Pin 5) | Supports system-level gain calibration to match host controller's absolute voltage standard (e.g., metrology-grade DMM). |
| Industry-standard SOIC-8 pinout | Allows drop-in upgrade from AD580, LM399, or MC1403 in existing PCB layouts without redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR441BRZ-R7 | 2.5 V output, 1 ppm/°C max tempco, 0.1 µV p-p (0.1–10 Hz), SOIC-8 | Requires level-shifting for 5 V systems; superior low-frequency noise but incompatible pinout and voltage. | Select when ultra-low drift (<1 ppm/°C) and sub-µV p-p noise are mandatory, and 2.5 V reference suffices. |
| REF5050AIDR | 5.000 V output, 3 ppm/°C max tempco, 4.8 µV p-p (0.1–10 Hz), SOIC-8, 10 mA drive | Higher initial accuracy (±0.5 mV), lower noise, but no TRIM or NOISE REDUCTION pins - fixed architecture. | Select when highest initial accuracy and lowest broadband noise are prioritized over field calibration flexibility. |
Compared with ADR441BRZ-R7 and REF5050AIDR, AD586LR-REEL uniquely balances laser-trimmed 5 V accuracy, user-accessible trim/noisefiltering pins, and proven buried Zener stability - making it optimal for cost-sensitive, field-calibratable 12–14 bit converter designs where SOIC-8 compatibility is required.

FAQ
What is the guaranteed initial accuracy of AD586LR-REEL at 25°C?
The AD586LR-REEL is laser trimmed to guarantee ±2.5 mV initial output voltage error at 25°C, corresponding to ±0.05% of nominal 5.000 V. This specification is fully tested and guaranteed per Analog Devices Rev. G datasheet Table 1 for the L grade in SOIC-8 packaging, and applies across all operating conditions unless otherwise noted.
Does AD586LR-REEL support both sourcing and sinking current on its VOUT pin?
Yes, AD586LR-REEL is specified to source or sink up to 10 mA continuously on Pin 6 (VOUT) while maintaining output regulation within datasheet limits. Sourcing performance shows 100 µV/mA load regulation; sinking exhibits 400 µV/mA - a key differentiator enabling bidirectional reference buffering in multiplexed converter systems.
Can AD586LR-REEL be used with a 1 µF noise reduction capacitor, and what is the impact on turn-on time?
Yes, AD586LR-REEL supports a 1 µF capacitor between Pin 8 (NOISE REDUCTION) and GND to reduce broadband noise to ~160 µV p-p. However, this increases electrical turn-on settling time to approximately 400 ms (to 0.01%), versus 60 µs without the capacitor - a critical timing consideration in power-cycled portable instruments.
Is the TRIM pin (Pin 5) of AD586LR-REEL compatible with standard resistor-divider calibration circuits?
Yes, the TRIM pin accepts an external resistor network that adjusts output voltage by ±6% (±300 mV), enabling precise calibration to 5.000 V or application-specific values like 5.12 V for binary scaling. The AD586LR-REEL datasheet Figure 6 provides the validated schematic, confirming compatibility with standard op-amp-assisted trim topologies.
What is the maximum input voltage rating for AD586LR-REEL, and what protection does it include?
AD586LR-REEL has an absolute maximum VIN rating of 36 V, with guaranteed operation from 10.8 V to 36 V. It includes indefinite short-circuit protection on VOUT to GND or VIN, and internal thermal shutdown. No external current-limiting resistor is required for safe operation under fault conditions per Absolute Maximum Ratings Table 3.
