Product details
Overview
AD586TQ/883B from Analog Devices is a high-precision, MIL-STD-883-compliant 5.000 V buried Zener voltage reference in an 8-lead CERDIP package (Q-8), specified for −55°C to +125°C operation, with ±7.5 mV max total output error, 10 ppm/°C max tempco, and 100 nV/√Hz noise density. It serves as a stable reference for 14-bit ADCs and DACs in aerospace and defense systems.
For engineers reviewing the AD586TQ/883B datasheet, AD586TQ/883B pinout, AD586TQ/883B application, or AD586TQ/883B equivalent, key selection criteria include military-grade temperature range compliance, low-drift performance over extended thermal extremes, noise reduction capability via external capacitor, and output sourcing/sinking up to 10 mA without external buffering.
Technical Context
The AD586TQ/883B uses a proprietary ion-implanted buried Zener diode combined with laser-trimmed thin-film resistors to achieve superior stability versus bandgap references. Its internal amplifier provides buffered 5 V output with rail-to-rail load capability and integrated noise reduction filtering via Pin 8.
It operates from 10.8 V to 36 V input, delivers ±100 µV/mA load regulation when sourcing 0–10 mA, and maintains 15 ppm/1000 hr long-term stability. The device supports fine-trim adjustment (±2% to ±6%) via Pin 5 and is qualified per MIL-STD-883B Method 5005 for screening and testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000 V ±7.5 mV over −55°C to +125°C - ensures system-level accuracy without recalibration across full military temperature range |
| Tempco | 10 ppm/°C max (−55°C to +125°C) - guarantees <±0.75 mV drift across full operating range |
| Noise Density | 100 nV/√Hz at 100 Hz - enables high-resolution data conversion without added filtering overhead |
| Load Drive | Sources or sinks up to 10 mA - eliminates need for external buffer in most precision converter applications |
| Quiescent Current | 2–3 mA - supports low-power avionics and embedded telemetry designs |
| Line Regulation | ±100 µV/V (10.8 V–36 V) - maintains output stability despite supply rail variation in harsh environments |
| Long-Term Stability | 15 ppm/1000 hr - reduces calibration frequency in mission-critical field-deployed equipment |
Pinout & Package
AD586TQ/883B is housed in an 8-lead hermetically sealed CERDIP package (Q-8), compliant with JEDEC MS-012AA, rated for −65°C to +150°C storage and qualified for high-reliability military applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7 | Factory Trim Pad (TP1) | No connection required; internal test points only - floating pads must remain unconnected to avoid performance degradation |
| 2 | VIN | Positive input supply (10.8 V–36 V); powers internal Zener and amplifier - requires local 0.1 µF bypass capacitor |
| 4 | GND | Analog ground reference; return path for VIN and output current - must be low-impedance, star-connected to system AGND |
| 5 | TRIM | Fine-adjustment node for ±2% to ±6% output scaling - connects to external resistor divider for system-level calibration |
| 6 | VOUT | Regulated 5.000 V output; capable of sourcing/sinking 10 mA - drives ADC/DAC reference inputs directly |
| 8 | NOISE REDUCTION | Filter node for external 1 µF capacitor to GND - reduces broadband noise by ~20% and suppresses Zener-related high-frequency components |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed buried Zener core | Enables 10 ppm/°C tempco and ±7.5 mV total error over −55°C to +125°C without external compensation |
| Noise reduction pin (Pin 8) | Supports 1 µF capacitor to reduce 1 MHz noise from 200 µV p-p to ~160 µV p-p - critical for SAR ADC SNR preservation |
| Output trim capability (Pin 5) | Allows ±2% to ±6% gain adjustment using external resistors - enables binary-scaled references (e.g., 5.12 V) without redesign |
| MIL-STD-883B compliance | Includes screening per Method 5005 (temperature cycling, burn-in, mechanical shock) - qualifies for flight-critical subsystems |
| Source/sink 10 mA output | Drives multiple converter references or precision current sources directly - avoids external op-amp stage and associated errors |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050QPWRQ1 | 5.0 V, 3 ppm/°C max (−40°C to +125°C), SOIC-8, automotive AEC-Q100 Grade 1 - lower tempco but limited to +125°C max | Qualified for automotive ECUs; lacks MIL-STD-883B screening and −55°C capability | Select for commercial-automotive use where extended cold start is not required |
| MAX6126ASA50+T | 5.0 V, 5 ppm/°C max (−40°C to +125°C), SOIC-8, ±0.05% initial accuracy - higher initial tolerance than AD586TQ/883B's ±0.15% | Optimized for industrial PLCs; no noise reduction pin or MIL-STD-883B compliance | Select when cost-sensitive industrial designs prioritize low initial error over military environmental robustness |

FAQ
What is the maximum operating temperature range for the AD586TQ/883B?
The AD586TQ/883B is fully specified and tested over −55°C to +125°C, with guaranteed performance including ±7.5 mV total output error and 10 ppm/°C max temperature coefficient across that full range. Its CERDIP package and MIL-STD-883B qualification ensure reliable operation in missile guidance systems and satellite power conditioning units.
Does the AD586TQ/883B require external capacitors for stability?
Yes - a 0.1 µF ceramic capacitor is required between VIN (Pin 2) and GND (Pin 4) for input decoupling. Additionally, a 1 µF capacitor between NOISE REDUCTION (Pin 8) and GND reduces broadband noise by ~20%, though the device remains stable without it. No output capacitor is needed for basic operation.
Can the AD586TQ/883B drive multiple ADC references simultaneously?
Yes - the AD586TQ/883B can source or sink up to 10 mA, enabling direct drive of multiple precision converters such as dual 14-bit SAR ADCs (e.g., AD7961) or stacked DAC configurations. Load regulation remains within ±100 µV/mA, preserving channel-to-channel matching in multi-channel data acquisition systems.
How does the TRIM pin (Pin 5) function in the AD586TQ/883B?
The TRIM pin allows ±2% to ±6% output voltage adjustment using an external resistor divider. For example, connecting a 10 kΩ potentiometer between VOUT and GND, with wiper to TRIM, enables precise calibration to 5.12 V for binary-scaled 12-bit systems. Adjustment does not degrade tempco or noise performance.
Is the AD586TQ/883B pin-compatible with other AD586 variants?
Yes - all AD586 variants (including AD586JQ, AD586LQ, AD586TQ) share identical Q-8 CERDIP pinout and electrical interface. The AD586TQ/883B differs only in its MIL-STD-883B screening, extended temperature grading, and tighter total error specification - allowing drop-in replacement in existing CERDIP-based designs requiring enhanced reliability.
