Product details
Overview
AD586JQ from Analog Devices is a precision 5 V buried Zener voltage reference IC in an 8-lead CERDIP (Q-8) package, delivering ±20 mV initial accuracy, 25 ppm/°C max temperature coefficient over 0°C to 70°C, 4 µV p-p low-frequency noise, and ±100 µV/V line regulation - used as a stable reference for high-resolution DACs and ADCs in test equipment and data acquisition systems.
For engineers reviewing the AD586JQ datasheet, AD586JQ pinout, AD586JQ application, or AD586JQ equivalent, key selection criteria include its laser-trimmed buried Zener architecture, noise reduction pin (Pin 8), external trim capability (Pin 5), sourcing/sinking ±10 mA output drive, and MIL-STD-883-compliant CERDIP packaging for ruggedized industrial and aerospace deployments.
Technical Context
The AD586JQ implements 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 provides 10 mA sourcing/sinking capability and supports dynamic load transients typical of 12–16-bit converters.
Temperature compensation is embedded in the Zener bias network, enabling guaranteed 25 ppm/°C max drift across 0°C to 70°C. The noise reduction pin (Pin 8) connects to an external 1 µF capacitor to form a low-pass filter that reduces broadband noise by ~20% without degrading DC accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±20 mV at 25°C - sets absolute accuracy floor for 12-bit+ converter full-scale calibration. |
| Tempco | 25 ppm/°C max (0°C to 70°C) - ensures ≤175 µV total drift across industrial temp range, critical for uncalibrated systems. |
| Low-Frequency Noise | 4 µV p-p (0.1 Hz to 10 Hz) - enables sub-LSB stability in precision digital multimeters and weigh scales. |
| Line Regulation | ±100 µV/V (10.8 V to 36 V input) - maintains reference integrity despite supply ripple in switching power supply environments. |
| Load Regulation | 100 µV/mA (sourcing, 0–10 mA) - supports direct driving of multiple converter reference inputs without buffering. |
| Quiescent Current | 2–3 mA - allows operation from 12 V or 15 V supplies with <30 mW total power consumption. |
| Short-Circuit Current | 45–60 mA - provides robust fault tolerance during board-level testing or transient overloads. |
Pinout & Package
AD586JQ is housed in an 8-lead Ceramic Dual In-Line Package (CERDIP, Q-8), compliant with MIL-STD-883, offering hermetic sealing and enhanced thermal stability for high-reliability applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7 | TP1 (Factory Trim Pad) | No connection required; internal test points only - floating pads must remain unconnected per datasheet. |
| 2 | VIN | Positive input supply (10.8 V to 36 V); powers internal Zener and amplifier - requires local 0.1 µF decoupling. |
| 4 | GND | Analog ground reference; must be tied to clean system ground plane to minimize noise coupling. |
| 5 | TRIM | External fine-adjust node; ±300 mV offset possible via resistor divider - enables binary-scaled references (e.g., 5.12 V). |
| 6 | VOUT | Regulated 5 V output; capable of sourcing or sinking up to 10 mA - drives DAC/ADC reference pins directly. |
| 8 | NOISE REDUCTION | Capacitor filter node; 1 µF to GND reduces 1 MHz noise from 200 µV p-p to ~160 µV p-p. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed buried Zener | Enables 25 ppm/°C max drift and 4 µV p-p noise - outperforms bandgap references in metrology-grade systems. |
| Noise reduction pin (Pin 8) | Supports external 1 µF capacitor to suppress high-frequency Zener noise without affecting DC accuracy or stability. |
| Output trim capability (Pin 5) | Allows ±6% gain adjustment (±300 mV at 5 V) for system-level calibration or nonstandard reference voltages. |
| MIL-STD-883 compliance | Validated for military/aerospace use with extended burn-in, hermetic Q-8 packaging, and −55°C to +125°C operating margin. |
| 10 mA sourcing/sinking | Drives multiple converter reference inputs simultaneously - eliminates need for external buffer amplifiers in multi-channel DAQ designs. |
Applications
| Digital Multimeter Reference | Automated Test Equipment (ATE) |

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 ±10 mV initial accuracy, 3 ppm/°C max tempco, SOIC-8 - lower drift but no noise reduction pin or MIL-STD-883 option. | Preferred for commercial-grade lab instruments where ultra-low drift outweighs hermetic packaging needs. | Select REF5050AIDR when sub-5 ppm/°C drift is mandatory and CERDIP reliability is not required. |
| ADR445BRZ | 5.000 V ±3 mV, 3 ppm/°C max, SOIC-8 - higher initial accuracy and lower noise (3.5 µV p-p), but no external trim or noise filter pin. | Suitable for medical imaging signal chains where low noise dominates over field calibration flexibility. | Choose ADR445BRZ for highest-accuracy commercial systems needing minimal post-manufacture adjustment. |
Compared with REF5050AIDR and ADR445BRZ, the AD586JQ trades tighter initial accuracy and lower drift for MIL-STD-883 qualification, external trim, and dedicated noise filtering - making it uniquely suited for upgradable, field-calibratable, and high-reliability embedded systems.

FAQ
What is the maximum input voltage rating for the AD586JQ?
The AD586JQ has an absolute maximum VIN-to-ground rating of 36 V. Operation above this voltage risks permanent damage. For reliable long-term performance, Analog Devices specifies operation between 10.8 V and 36 V, with optimal stability observed at 12 V or 15 V supplies. The AD586JQ's internal Zener and buffer are designed to maintain 5.000 V output accuracy and low drift within this validated range.
Does the AD586JQ require external components to function as a basic 5 V reference?
No, the AD586JQ operates as a complete 5 V reference with only VIN (Pin 2) and GND (Pin 4) connections - no external capacitors or resistors are needed for nominal operation. However, a 0.1 µF ceramic capacitor from VIN to GND is strongly recommended for supply decoupling, and the noise reduction pin (Pin 8) accepts a 1 µF capacitor if lower broadband noise is required. The TRIM pin (Pin 5) remains unconnected unless fine adjustment is needed.
Can the AD586JQ drive multiple ADC reference inputs simultaneously?
Yes, the AD586JQ can source or sink up to 10 mA, enabling direct connection to multiple high-resolution ADC reference inputs - for example, four 14-bit SAR ADCs each drawing 2 mA. Load regulation is specified at 100 µV/mA, so driving 8 mA yields ≤800 µV total deviation. For >10 mA loads or stringent settling time requirements, an external buffer amplifier is advised.
Is the AD586JQ pin-compatible with other AD586 grade variants like AD586JR or AD586JN?
Yes, all AD586 variants - including AD586JQ (CERDIP), AD586JR (SOIC), and AD586JN (PDIP) - share identical 8-pin functionality and pinout (N-8/Q-8/R-8). Pin 1 is TP1 (no connect), Pin 2 is VIN, Pin 4 is GND, Pin 5 is TRIM, Pin 6 is VOUT, and Pin 8 is NOISE REDUCTION. This uniformity allows drop-in replacement across packages when mechanical or reliability requirements change.
What is the purpose of the three unconnected test pads (Pins 1, 3, and 7) on the AD586JQ?
Pins 1, 3, and 7 on the AD586JQ are internal factory trim pads (TP1) used during wafer-level laser trimming and final test. Analog Devices explicitly states "NO CONNECTIONS SHOULD BE MADE TO THESE POINTS." They must remain floating - connecting them risks altering internal bias conditions, degrading accuracy, or causing instability. PCB layouts should treat these as dummy pads with no routing or solder mask openings.
