Product details
Overview
AD586AR-REEL from Analog Devices is a precision 5.000 V buried Zener voltage reference IC in SOIC-8 package, delivering ±2.5 mV initial accuracy (L grade), 5 ppm/°C max temperature coefficient over 0°C to 70°C, 4 µV p-p low-frequency noise, and ±10 mA output sourcing/sinking 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 AD586AR-REEL datasheet, AD586AR-REEL pinout, AD586AR-REEL application, or AD586AR-REEL equivalent, key selection criteria include initial voltage error, tempco across operating range, noise reduction pin usability, load regulation performance, and compatibility with precision converter biasing schemes.
Technical Context
The AD586AR-REEL implements a proprietary ion-implanted buried Zener diode core with laser-trimmed thin-film resistors, enabling superior drift and noise performance versus bandgap references. Its internal buffer amplifier provides rail-to-rail output drive and supports both sourcing and sinking up to ±10 mA.
It features two dedicated auxiliary terminals: Pin 5 (TRIM) enables external fine adjustment of output voltage by ±300 mV, and Pin 8 (NOISE REDUCTION) accepts a 1 µF capacitor to ground for reducing broadband noise by ~20% - critical for high-resolution converter applications requiring sub-LSB stability.
Key Specifications

|---|---|
| Output Voltage | 5.000 V ±2.5 mV at 25°C - ensures ≤0.05% absolute error in calibration-critical signal chains |
| Tempco | 5 ppm/°C max (0°C to 70°C) - guarantees ≤0.35 mV total drift across industrial ambient range |
| Low-Frequency Noise | 4 µV p-p (0.1 Hz to 10 Hz) - enables <16-bit effective resolution without external filtering |
| Output Drive | ±10 mA sourcing/sinking - supports direct interface to multiple DAC reference inputs or op-amp bias networks |
| Line Regulation | ±100 µV/V (10.8 V to 36 V input) - maintains stability under wide supply variation common in mixed-signal PCBs |
| Long-Term Stability | 15 ppm/1000 hr - ensures <0.1% output shift over 1 year in deployed instrumentation |
| Quiescent Current | 2–3 mA - allows use in low-power portable precision systems without thermal derating |
Pinout & Package
AD586AR-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. Pin 1 is marked by a beveled corner or dot.

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 | 5.000 V bandgap reference; 3 ppm/°C max tempco; 5.6 µV p-p noise; 10 mA drive; SOIC-8 | Lower tempco but higher noise; no TRIM or NOISE REDUCTION pins; requires external filter for <16-bit use | Prefer when ultra-low drift dominates over noise sensitivity and trimming flexibility is unnecessary |
| ADR445BRZ | 5.000 V XFET reference; 3 ppm/°C max tempco; 1.75 µV p-p noise; 10 mA drive; SOIC-8 | Lower noise than AD586AR-REEL but no external trim; higher cost; limited long-term stability spec (12 ppm/1000 hr) | Prefer when lowest possible noise is mandatory and system-level calibration is handled elsewhere |
Compared with REF5050AIDR and ADR445BRZ, the AD586AR-REEL offers unique external trim and noise reduction functionality at lower cost, making it optimal for systems requiring field calibration or adaptive noise filtering - while REF5050AIDR trades noise for simplicity, and ADR445BRZ targets ultra-low-noise niche applications at premium price.

FAQ
What is the initial accuracy and temperature coefficient of the AD586AR-REEL?
The AD586AR-REEL is the L-grade variant, specified for ±2.5 mV initial output voltage error at 25°C and a maximum temperature coefficient of 5 ppm/°C over the 0°C to 70°C operating range. This corresponds to a worst-case total drift of ±0.35 mV across its specified temperature span, confirmed in Table 1 of the Rev. G datasheet.
Can the AD586AR-REEL be used to generate a negative reference voltage?
Yes, the AD586AR-REEL can be configured as a −5.000 V reference by grounding the VOUT pin (Pin 6), connecting VIN (Pin 2) to a +6 V to +30 V supply, and tying the GND pin (Pin 4) through a current-setting resistor to a negative supply (e.g., −15 V). The AD586AR-REEL maintains its specified tempco and long-term stability in this inverted configuration, as documented in Figure 19 of the datasheet.
Does the AD586AR-REEL require external components for basic operation?
No, the AD586AR-REEL operates stand-alone with only VIN (Pin 2) and GND (Pin 4) connections - VOUT (Pin 6) delivers 5.000 V directly. External components are optional: a 1 µF capacitor on Pin 8 improves noise, and a resistor network on Pin 5 enables fine trim. These are not needed for nominal operation, per the "Applying the AD586" section.
What is the purpose of Pins 1, 3, and 7 on the AD586AR-REEL?
Pins 1, 3, and 7 are factory test pads (TP1) used during wafer probing and final test. They are internal trim points with no functional role in circuit operation. The datasheet explicitly states "NO CONNECTIONS… SHOULD BE MADE TO THESE POINTS" - they must remain unconnected on the PCB, except for non-functional dummy pads.
How does the noise reduction pin (Pin 8) affect turn-on time?
Adding a 1 µF capacitor to Pin 8 (NOISE REDUCTION) increases the AD586AR-REEL's turn-on settling time from ~60 µs (0.01% error) to approximately 400 ms due to added capacitive loading on the internal Zener current source. This trade-off is intentional: the capacitor filters high-frequency noise but slows transient response, as shown in Figure 11 of the Rev. G datasheet.
