Product details
Overview
AD586BR-REEL7 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 ±2.5 mV initial accuracy and 5 ppm/°C max temperature coefficient. It delivers low 4 µV p-p (0.1–10 Hz) noise, supports ±10 mA output sourcing/sinking, and features dedicated noise reduction and fine-trim pins for high-resolution DAC/ADC reference applications in test equipment and data acquisition systems.
For engineers reviewing the AD586BR-REEL7 datasheet, AD586BR-REEL7 pinout, AD586BR-REEL7 application, or AD586BR-REEL7 equivalent, this page provides verified specifications, SOIC-8 terminal mapping, real-world use cases in precision converter systems, and validated alternative references - all grounded in Analog Devices' Rev. G datasheet and official ordering guide.
Technical Context
The AD586BR-REEL7 implements a proprietary ion-implanted buried Zener diode core with laser-trimmed thin-film resistors, enabling superior long-term stability (15 ppm/1000 hr) and lower drift/noise versus bandgap references. Its integrated buffer amplifier provides robust load regulation (100 µV/mA sourcing) and fast turn-on (60 µs to 0.01% without CN).
It supports two optional enhancements: a 1 µF capacitor on Pin 8 reduces broadband noise to ~160 µV p-p (1 MHz), while external resistor networks on Pin 5 enable ±300 mV fine trim without degrading TC or stability - both functions validated across the B-grade temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±2.5 mV at 25°C - ensures ≤0.05% absolute error for 12-bit+ converter full-scale calibration. |
| Temp Coefficient | 5 ppm/°C max (0°C to 70°C) - guarantees ≤0.35 mV total drift over industrial ambient range. |
| Output Noise | 4 µV p-p (0.1–10 Hz); 100 nV/√Hz @100 Hz - enables <16-bit ENOB in low-frequency precision digitization. |
| Load Regulation | 100 µV/mA (0–10 mA sourcing) - maintains reference integrity under dynamic DAC current draw. |
| Quiescent Current | 2–3 mA - allows stable operation from 12–15 V supplies with <30 mW power consumption. |
| Trim Range | ±300 mV via external resistor on TRIM pin - supports binary-scaled references (e.g., 5.12 V) without recalibration. |
| Short-Circuit Current | 45–60 mA - protects against transient faults while sustaining output during overload recovery. |
Pinout & Package

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 TC, 5 µV p-p noise, 10 mA drive, SOIC-8. | Better TC spec but higher 1/f noise; less suitable for sub-10 Hz biomedical sensing. | Choose REF5050AIDR for wider temp range (−40°C to +125°C) and lower power (950 µA), but verify noise floor impact. |
| ADR445ARMZ | Buried Zener; 3 ppm/°C TC, 1.8 µV p-p noise, 10 mA drive, SOIC-8. | Lower noise than AD586BR-REEL7 but requires 12 V min supply and has no trim pin. | Choose ADR445ARMZ when ultra-low noise dominates design priority and fine adjustment is unnecessary. |
Compared with REF5050AIDR and ADR445ARMZ, AD586BR-REEL7 uniquely combines factory-laser-trimmed Zener accuracy, user-accessible noise reduction and fine-trim pins, and proven 0°C to 70°C stability - making it optimal for cost-sensitive, high-volume instrumentation where configurability and legacy compatibility matter.

FAQ
What is the initial output voltage tolerance of AD586BR-REEL7 at 25°C?
The AD586BR-REEL7 has a guaranteed initial output voltage of 5.000 V ±2.5 mV at 25°C, corresponding to the "L" grade specification per Analog Devices' Rev. G datasheet Table 1. This ±0.05% tolerance is achieved via laser wafer trimming of thin-film resistors and is tested on all production units.
Can AD586BR-REEL7 operate with input voltages below 12 V?
No - AD586BR-REEL7 requires a minimum input voltage of 10.8 V for guaranteed performance across its 0°C to 70°C range, as specified in the Absolute Maximum Ratings and Load Regulation sections. Operation below 10.8 V risks loss of regulation, increased drift, and failure to maintain ±2.5 mV accuracy.
Does AD586BR-REEL7 support negative reference generation?
Yes - AD586BR-REEL7 can generate a precision −5.000 V output by connecting VIN to +6 V to +30 V, grounding VOUT, and tying GND (Pin 4) through a current-setting resistor to a −15 V rail. The net current through the device must remain between 2.5 mA and 10.0 mA to preserve TC and stability, as detailed in Figure 19 of the datasheet.
What is the purpose of the NOISE REDUCTION pin (Pin 8) on AD586BR-REEL7?
The NOISE REDUCTION pin (Pin 8) on AD586BR-REEL7 accepts a 1 µF capacitor to ground to form a low-pass filter with internal Zener resistances, reducing broadband noise (e.g., 1 MHz) from ~200 µV p-p to ~160 µV p-p. This function is fully characterized and recommended in the Noise Performance section for applications demanding ultra-low noise floors.
Is AD586BR-REEL7 pin-compatible with older AD586 variants in SOIC packages?
Yes - AD586BR-REEL7 uses the standard 8-lead SOIC (R-8) footprint defined in JEDEC MS-012AA and shares identical pinout, electrical behavior, and thermal characteristics with AD586JR, AD586KR, and AD586LR in the same package. No PCB layout changes are required for drop-in replacement within the same grade family.
