Product details
Overview
AD586BRZ-REEL from Analog Devices is a precision 5.000 V buried Zener voltage reference IC in an 8-lead SOIC package, specified for −40°C to +85°C operation (B grade), with ±5 mV initial accuracy, 5 ppm/°C max temperature coefficient, 4 µV p-p low-frequency noise, and ±10 mA output sourcing/sinking capability. It serves as a high-stability reference for 12–14-bit ADCs/DACs in industrial data acquisition systems.
For engineers reviewing the AD586BRZ-REEL datasheet, AD586BRZ-REEL pinout, AD586BRZ-REEL application, or AD586BRZ-REEL equivalent, key selection criteria include its laser-trimmed 5 V output stability, noise reduction pin (Pin 8), external trim capability (Pin 5), load regulation of 100 µV/mA, and compatibility with precision converter biasing and stacked reference topologies.
Technical Context
The AD586BRZ-REEL implements a proprietary ion-implanted buried Zener diode with laser-trimmed thin-film resistors, delivering lower drift and noise than bandgap references. Its internal buffer amplifier enables ±10 mA output drive while maintaining <2.5 mV total error over −40°C to +85°C.
It features dedicated terminals for noise filtering (Pin 8, accepts 1 µF capacitor to ground) and fine output adjustment (Pin 5, ±6% gain trim range). The device operates from 10.8 V to 36 V input and achieves 0.01% turn-on settling in 60 µs without noise capacitor-or 400 ms with it-enabling rapid system calibration cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±5 mV at 25°C - guarantees absolute accuracy within 0.1% for high-resolution converter referencing. |

| Noise (0.1–10 Hz) | 4 µV p-p - supports 16-bit effective resolution in low-frequency measurement systems without external filtering. |
| Load Regulation | 100 µV/mA (sourcing) - maintains voltage stability under dynamic DAC/ADC current transients up to 10 mA. |
| Quiescent Current | 2–3 mA - enables low-power operation in battery-backed or energy-constrained instrumentation. |
| Line Regulation | ±100 µV/V (10.8–36 V) - rejects supply ripple in unregulated or wide-input industrial power rails. |

Pinout & Package
AD586BRZ-REEL is housed in an 8-lead narrow-body SOIC (R-8) package per JEDEC MS-012AA, with 1.27 mm pitch, 5.00 mm × 4.00 mm body size, and 1.75 mm maximum height. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Factory Test Point (TP1) | No connection required; internal trim pad - must remain floating per datasheet. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050IDR | 5 V, 3 ppm/°C max, 1.6 µV p-p noise, 10 mA drive, SOIC-8 - uses buried Zener but with integrated noise filter and lower quiescent current (950 µA). | Better noise and drift specs, but lacks TRIM pin; not suitable for systems requiring field calibration to non-standard voltages. | Select REF5050IDR when lowest possible noise and drift are mandatory and external trimming is unnecessary. |
| ADR445ARMZ | 5 V, 3 ppm/°C max, 2.8 µV p-p noise, 10 mA drive, SOIC-8 - CMOS-based XFET reference with superior long-term stability (5 ppm/1000 hr) but higher cost. | XFET architecture offers better PSRR and lower thermal hysteresis; no noise reduction pin; incompatible with negative reference configurations. | Select ADR445ARMZ for ultra-stable lab-grade instruments where lifetime calibration drift is the dominant concern. |
Compared with REF5050IDR and ADR445ARMZ, the AD586BRZ-REEL uniquely combines external trim capability, noise reduction pin, and proven buried Zener performance at lower cost - making it optimal for industrial converters requiring field-adjustable, low-drift 5 V references.

FAQ
What is the operating temperature range for the AD586BRZ-REEL?
The AD586BRZ-REEL is rated for −40°C to +85°C operation (B grade), with guaranteed 5 ppm/°C max temperature coefficient and ±5 mV initial output error across this full industrial range. Its specified performance remains valid within these limits, and it can function outside them - though accuracy degrades beyond the specified bounds.
Does the AD586BRZ-REEL require external components to function?
No, the AD586BRZ-REEL operates as a complete 5 V reference with only VIN (10.8–36 V) and GND connections. However, best practice requires a 0.1 µF ceramic capacitor from VIN to GND. Optional components include a 1 µF capacitor on Pin 8 for noise reduction and a resistor network on Pin 5 for fine trimming - neither is mandatory for basic functionality.
Can the AD586BRZ-REEL be used to generate a negative reference voltage?
Yes, the AD586BRZ-REEL can configure a precision −5.000 V output by grounding VOUT, connecting VIN to ≥6 V, and tying GND (Pin 4) through a resistor to a −15 V rail. This reverse configuration maintains the same temperature coefficient and long-term stability as the standard +5 V mode, provided net current stays between 2.5 mA and 10 mA.
What is the purpose of the TRIM pin (Pin 5) on the AD586BRZ-REEL?
The TRIM pin (Pin 5) enables external fine adjustment of the AD586BRZ-REEL output voltage over a ±6% range (4.7–5.3 V), supporting system-level calibration to exact 5.000 V or binary-aligned values like 5.12 V. It interfaces with a simple resistor divider and does not affect temperature drift, noise, or load regulation performance.
How does the NOISE REDUCTION pin (Pin 8) improve performance of the AD586BRZ-REEL?
The NOISE REDUCTION pin (Pin 8) connects to the buried Zener's bias node; adding a 1 µF capacitor to ground forms a low-pass filter that reduces high-frequency noise - cutting 1 MHz broadband noise from 200 µV to 160 µV p-p. This preserves SNR in sensitive ADC front-ends without altering DC accuracy or temperature behavior of the AD586BRZ-REEL.
