Product details
Overview
AD586KR-REEL from Analog Devices is a precision 5.000 V buried Zener voltage reference IC in an 8-lead SOIC package, specified for 0°C to 70°C operation with ±5 mV initial output error and 15 ppm/°C max temperature coefficient. It delivers low noise (4 µV p-p, 0.1 Hz–10 Hz), supports ±10 mA load current, and features dedicated noise reduction and output trim pins for high-accuracy data converter applications.
For engineers reviewing the AD586KR-REEL datasheet, AD586KR-REEL pinout, AD586KR-REEL application, or AD586KR-REEL equivalent, this page provides verified specifications, real-world use cases in DAC/ADC systems, pin-level design meaning, and validated alternative options for precision analog signal chains requiring stable 5 V references.
Technical Context
The AD586KR-REEL uses a proprietary ion-implanted buried Zener diode with laser-trimmed thin-film resistors to achieve superior drift and noise performance versus bandgap references. Its internal buffer amplifier enables sourcing/sinking up to ±10 mA while maintaining <100 µV/mA load regulation over temperature.
It integrates two key configurable functions: Pin 8 (NOISE REDUCTION) accepts a 1 µF capacitor to form a low-pass filter reducing broadband noise to ~160 µV p-p; Pin 5 (TRIM) allows external fine adjustment of output voltage by ±300 mV with minimal impact on stability or drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±5 mV at 25°C - ensures direct compatibility with 12-bit DACs requiring ≤0.12% full-scale reference accuracy. |
| Temp Coefficient | 15 ppm/°C max (0°C to 70°C) - limits total error to ≤1.05 mV across industrial ambient range. |
| Output Noise | 4 µV p-p (0.1 Hz–10 Hz); 100 nV/√Hz @ 100 Hz - enables high-resolution ADCs without external filtering. |
| Load Current | ±10 mA sourcing/sinking capability - supports driving multiple converter reference inputs or op-amp bias networks. |
| Quiescent Current | 2–3 mA - enables low-power precision systems with 12–15 V supply without thermal derating. |
| Line Regulation | ±100 µV/V (10.8–36 V input) - maintains accuracy across wide input voltage variations common in unregulated supplies. |
| Long-Term Stability | 15 ppm/1000 hr - guarantees <0.015% output drift per 1000 hours, critical for calibration-critical instrumentation. |
Pinout & Package
AD586KR-REEL is housed in an 8-lead SOIC (R-8) package per JEDEC MS-012AA, with 1.27 mm pitch, 5.00 mm × 4.00 mm body, and 1.75 mm maximum height. Pins 1, 3, and 7 are factory test points - no connection permitted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | TP1 | Internal factory trim pad - must remain unconnected; PCB pad may be used as dummy ground fill only. |
| Pin 2 | VIN | Positive supply input (10.8–36 V); powers internal Zener and buffer - requires local 0.1 µF bypass to GND. |
| Pin 3 | TP1 | Internal factory trim pad - must remain unconnected; no routing or soldering allowed. |
| Pin 4 | GND | Analog ground reference - must connect to clean system AGND plane with low-impedance path to VIN bypass cap. |
| Pin 5 | TRIM | External fine-adjust node - connects to resistor divider for ±300 mV output offset without degrading TC or noise. |
| Pin 6 | VOUT | Regulated 5.000 V output - capable of sourcing/sinking ±10 mA; layout must minimize trace inductance for dynamic loads. |
| Pin 7 | TP1 | Internal factory trim pad - must remain unconnected; not usable for test or debug. |
| Pin 8 | NOISE REDUCTION | Filter node for 1 µF capacitor to GND - reduces 1 MHz noise from 200 µV p-p to 160 µV p-p and suppresses Zener high-frequency artifacts. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed buried Zener | Enables 5.000 V ±5 mV initial accuracy and 15 ppm/°C tempco without external compensation components. |
| Noise reduction pin (Pin 8) | Allows 1 µF capacitor to ground to reduce broadband noise by ~20% while preserving DC accuracy and settling time. |
| Output trim capability (Pin 5) | Supports ±300 mV fine adjustment via external resistor network - essential for binary-scaled references (e.g., 5.12 V). |
| ±10 mA output drive | Eliminates need for external buffer op-amps when driving multiple 12-/14-bit DAC reference inputs simultaneously. |
| MIL-STD-883-compliant variants available | Confirms suitability for aerospace/defense applications where reliability under shock, vibration, and extended temperature stress is mandatory. |
Applications
| High-Accuracy Data Acquisition | Calibration Equipment |
|---|---|
|

IC Role / Device Role / Timing Role: Master reference source feeding precision resistor ladder and auto-zero op-amp circuitry. Use Value: 15 ppm/1000 hr long-term stability meets ANSI C12.20 Class 0.1 meter standards; TRIM pin enables periodic recalibration without hardware change. |
| Industrial DAC-Based Control | Stacked Multi-Voltage Reference |
|
Use Scenario: PLC analog output card using 12-bit multiplying CMOS DAC (e.g., AD7545) to generate 0–10 V control signals. IC Role / Device Role / Timing Role: Precision 5 V reference for DAC VREF input, with NOISE REDUCTION pin filtered for EMI immunity in noisy factory environments. Use Value: ±10 mA drive capability powers DAC reference input and internal op-amp bias; 100 nV/√Hz spectral density avoids gain error in closed-loop servo feedback paths. |
Use Scenario: Test equipment requiring simultaneous 5 V, 10 V, and 15 V precision references from single supply rail. IC Role / Device Role / Timing Role: One of three cascaded AD586KR-REEL units in series-connected configuration, each regulating its own output stage. Use Value: Identical tempco and noise specs across all units ensure matched drift and ripple rejection; SOIC packaging enables compact 3×1 PCB layout with shared thermal mass. |
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 | 2.5 V output, 1.5 ppm/°C max tempco, 1.8 µV p-p noise - lower drift but fixed 2.5 V output requiring external gain for 5 V systems. | Best suited for new designs targeting ultra-low-drift 2.5 V references; not drop-in for 5 V-referenced DACs without level-shifting circuitry. | Select ADR441BRZ only if system architecture permits 2.5 V reference + gain stage; otherwise AD586KR-REEL remains optimal for direct 5 V replacement. |
| REF5050AIDR | 5 V output, 3 ppm/°C max tempco, 5 µV p-p noise - tighter initial accuracy (±1 mV) and lower drift, but higher quiescent current (4.5 mA). | Preferred for metrology-grade instruments demanding <0.5 ppm/°C total error; less suitable for battery-powered devices due to higher power draw. | Choose REF5050AIDR when absolute drift budget is <3 ppm/°C and supply headroom allows 4.5 mA; retain AD586KR-REEL for cost-sensitive, moderate-accuracy industrial controls. |
Compared with ADR441BRZ and REF5050AIDR, the AD586KR-REEL offers the only combination of native 5 V output, SOIC packaging, ±10 mA drive, and proven field reliability in legacy converter designs - making it the most practical upgrade path for existing 5 V reference circuits without layout changes.

FAQ
What is the maximum input voltage rating for the AD586KR-REEL?
The AD586KR-REEL has an absolute maximum VIN rating of 36 V. Operation above 36 V risks permanent damage. For reliable long-term performance, Analog Devices specifies 10.8 V to 36 V as the functional input range, with line regulation tested across this span. The device draws only 2–3 mA quiescent current, so power dissipation remains well within safe limits even at 36 V input.
Can the AD586KR-REEL be used as a negative reference voltage source?
Yes, the AD586KR-REEL can generate a precision −5.000 V output by connecting VIN to ≥6 V, grounding VOUT, and tying GND (Pin 4) through a resistor to a −15 V supply. This configuration maintains the same 15 ppm/°C tempco and 15 ppm/1000 hr long-term stability as the standard +5 V mode, provided net current through the device stays between 2.5 mA and 10.0 mA.
Does the AD586KR-REEL require external capacitors for stability?
The AD586KR-REEL is internally compensated and operates stably without external output capacitors. However, a 0.1 µF ceramic capacitor between VIN and GND is mandatory for supply decoupling. Additionally, a 1 µF capacitor from Pin 8 (NOISE REDUCTION) to GND is optional but recommended to reduce broadband noise by ~20% - it does not affect DC stability or regulation.
What is the purpose of the TRIM pin (Pin 5) on the AD586KR-REEL?
The TRIM pin (Pin 5) enables external fine adjustment of the AD586KR-REEL output voltage by ±300 mV using a simple resistor network, as shown in Figure 6 of the datasheet. This allows precise calibration to 5.000 V against a master standard or setting non-standard values like 5.12 V for binary-scaled systems - all without degrading temperature coefficient or long-term stability.
Is the AD586KR-REEL pin-compatible with older AD586 variants in SOIC packages?
Yes, the AD586KR-REEL shares identical pinout, footprint, and electrical behavior with all other AD586 variants in the R-8 (SOIC) package, including AD586JR, AD586LR, and AD586MR. All use the same 8-pin configuration with VIN (Pin 2), GND (Pin 4), TRIM (Pin 5), VOUT (Pin 6), and NOISE REDUCTION (Pin 8), enabling direct substitution within the same grade family.
