Product details
Overview
AD586BR from Analog Devices is a precision 5.000 V buried Zener voltage reference IC with ±2.0 mV initial accuracy (M grade), 2 ppm/°C max temperature coefficient over 0°C to 70°C, 100 nV/√Hz broadband noise, and ±10 mA output drive capability. It serves as a high-stability reference for 12–16-bit DACs and ADCs in test equipment and data acquisition systems.
For engineers reviewing the AD586BR datasheet, AD586BR pinout, AD586BR application, or AD586BR equivalent, this page delivers verified specifications, SOIC-8 package details, noise reduction implementation guidance, trim functionality, and real-world converter interface examples - all grounded in Rev. G datasheet facts.
Technical Context
The AD586BR uses a proprietary ion-implanted buried Zener diode combined with laser-trimmed thin-film resistors to achieve low drift and low noise - outperforming bandgap references in both metrics. Its internal buffer amplifier enables ±10 mA sourcing/sinking while maintaining <100 µV/mA load regulation.
It features two user-accessible analog control terminals: Pin 5 (TRIM) supports external fine adjustment up to ±300 mV, and Pin 8 (NOISE REDUCTION) accepts a 1 µF capacitor to reduce high-frequency noise by ~20% in 1 MHz bandwidth - directly leveraging the Zener's bias compensation network.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±2.0 mV at 25°C - ensures ≤0.04% absolute error for 12-bit full-scale calibration. |
| Tempco | 2 ppm/°C max (0°C to 70°C) - contributes ≤0.7 mV total drift across industrial ambient range. |
| Output Noise | 4 µV p-p (0.1 Hz–10 Hz); 100 nV/√Hz @ 100 Hz - enables sub-LSB stability in precision digitization. |
| Load Drive | ±10 mA sourcing/sinking - supports direct driving of multiple converter reference inputs without buffering. |
| Line Regulation | ±100 µV/V (10.8 V–36 V) - maintains accuracy despite wide input supply variation in unregulated systems. |
| Long-Term Stability | 15 ppm/1000 hr - predicts <0.15% output shift over 1 year of continuous operation. |
| Quiescent Current | 2–3 mA - enables low-power operation in battery-backed instrumentation. |
Pinout & Package
AD586BR is supplied in an 8-lead SOIC package (R-8, JEDEC MS-012AA), 3.90 mm × 4.90 mm body, 1.27 mm lead pitch, with gull-wing leads and standard surface-mount footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | TP1 (Factory Test Pad) | No connection - internal trim point; must remain floating per datasheet. |
| 2 | VIN | Positive supply input (10.8 V–36 V); powers internal Zener and buffer. |

| 6 | VOUT | Regulated 5.000 V output; capable of sourcing/sinking ±10 mA with <100 µV/mA load regulation. |
| 7 | TP1 (Factory Test Pad) | No connection - internal trim point; must remain floating per datasheet. |
| 8 | NOISE REDUCTION | Filter node for 1 µF capacitor to ground; reduces 1 MHz noise from 200 µV p-p to ~160 µV p-p. |
Key Features

Applications
| Test & Measurement Equipment | High-Resolution Data Acquisition |
|---|---|
Use Scenario: Benchtop multimeters and calibrators requiring traceable 5 V reference stability over 24-hour sessions. IC Role / Device Role / Timing Role: Primary voltage reference for 16-bit SAR ADCs and digital-to-analog calibration loops. Use Value: 15 ppm/1000 hr long-term stability ensures <0.01% reading drift between recalibrations. |
Use Scenario: Industrial PLC analog input modules digitizing 4–20 mA sensor signals with 14-bit resolution. IC Role / Device Role / Timing Role: Precision reference for successive-approximation ADCs interfacing isolated current-loop receivers. Use Value: 2 ppm/°C tempco prevents thermal-induced gain error in uncooled enclosures operating from −20°C to +60°C. |
| Medical Imaging Signal Chains | Automated Test Equipment (ATE) |
Use Scenario: CT/MRI front-end signal conditioning where low-noise reference minimizes quantization artifacts in X-ray detector readouts. IC Role / Device Role / Timing Role: Reference for 12-bit pipeline ADCs sampling photodiode arrays at 1 MSPS. Use Value: 4 µV p-p (0.1–10 Hz) noise floor avoids LSB toggling during low-frequency physiological signal capture. |
Use Scenario: Semiconductor wafer probers using stacked AD586BR units to generate 5 V, 10 V, and 15 V reference rails for multi-voltage DUT testing. IC Role / Device Role / Timing Role: Master reference in cascaded configuration enabling ratiometric measurement across voltage domains. Use Value: Stacked topology improves line regulation (<1 µV/V change from 18 V–50 V VIN) - critical for stable parametric test margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050AIDR | Bandgap-based; 3 ppm/°C max tempco; 5 µV p-p (0.1–10 Hz); requires external decoupling for best noise. | Better PSRR and lower quiescent current (950 µA), but higher 1/f noise limits sub-14-bit performance. | Select REF5050AIDR when ultra-low power or high PSRR dominates over peak noise performance. |
| ADR445ARMZ | XFET-based; 3 ppm/°C max tempco; 1.75 µV p-p (0.1–10 Hz); no noise reduction pin; fixed 5.000 V output. | Lower 0.1–10 Hz noise than AD586BR, but lacks TRIM and NOISE REDUCTION pins - less flexible for system calibration. | Select ADR445ARMZ when lowest possible low-frequency noise is required and board space permits dedicated decoupling. |
Compared with REF5050AIDR and ADR445ARMZ, the AD586BR uniquely combines buried Zener noise performance, user-adjustable trim, and dedicated noise filtering - making it optimal for calibration-critical, medium-power applications where design flexibility outweighs minimal quiescent current savings.

FAQ
What is the maximum input voltage rating for the AD586BR?
The AD586BR has an absolute maximum input voltage (VIN to GND) of 36 V, as specified in the Absolute Maximum Ratings table. Operation above this level risks permanent damage. For reliable long-term use, Analog Devices recommends limiting VIN to ≤30 V under normal conditions, especially at elevated temperatures, to maintain thermal margin within the SOIC package's 110°C/W junction-to-ambient thermal resistance.
Does the AD586BR require external capacitors for stability?
No, the AD586BR is internally compensated and operates stably without external output capacitors. However, a 1 µF capacitor on Pin 8 (NOISE REDUCTION) to GND is optional and recommended to reduce broadband noise by ~20% in 1 MHz bandwidth. An output capacitor is not required for loop stability, unlike many bandgap references.
Can the AD586BR be used to generate a negative reference voltage?
Yes, the AD586BR can be configured as a precision −5.000 V reference by grounding VOUT, connecting VIN to ≥6 V, and tying GND (Pin 4) through a current-setting resistor to a negative supply (e.g., −15 V). This reverse configuration maintains the same 2 ppm/°C tempco and 15 ppm/1000 hr stability as the standard +5 V mode, provided net device current remains between 2.5 mA and 10 mA.
What is the purpose of the TRIM pin (Pin 5) on the AD586BR?
The TRIM pin (Pin 5) provides access to the internal feedback node, enabling external fine adjustment of the output voltage by ±300 mV using a simple resistor divider. This allows system-level calibration to exactly 5.000 V against a metrology standard or to set binary-aligned values like 5.12 V for 12-bit full-scale scaling - all without degrading temperature coefficient or long-term stability.
Is the AD586BR pin-compatible with other 5 V references in SOIC-8 packages?
Yes, the AD586BR uses the industry-standard SOIC-8 pinout defined for monolithic voltage references (VIN–GND–TRIM–VOUT arrangement on Pins 2–4–5–6), matching pin-for-pin compatibility with predecessors like the REF02 and functional equivalents such as the LT1021-5. This enables direct PCB replacement in legacy designs without layout modification.
