Product details
Overview
AD587JR-REEL from Analog Devices is a precision 10 V monolithic voltage reference IC using a buried Zener diode architecture, laser-trimmed for ±10 mV initial accuracy and 20 ppm/°C temperature coefficient over 0°C to 70°C. It delivers low-noise (4 μV p-p, 0.1 Hz–10 Hz), low-quiescent-current (≤4 mA), and features dedicated noise-reduction and output-trim pins. It serves as a high-stability external reference for 12-bit to 16-bit DACs and ADCs in test equipment and data acquisition systems.
For engineers reviewing the AD587JR-REEL datasheet, AD587JR-REEL pinout, AD587JR-REEL application, or AD587JR-REEL equivalent, key selection criteria include its SOIC_N package compatibility, 10 V output stability under load and temperature variation, noise-reduction capacitor interface, fine-trim capability, and suitability for high-resolution converter biasing in industrial and instrumentation designs.
Technical Context
The AD587JR-REEL integrates a proprietary ion-implanted buried Zener diode with laser-trimmed thin-film resistors and an internal buffer amplifier. Its core architecture enables superior long-term stability (±15 ppm/1000 hr) and low thermal drift without external compensation components.
It supports two critical analog design functions: (1) direct 10 V reference output with optional fine trimming via Pin 5 (±3% gain adjust), and (2) active noise reduction via external capacitor on Pin 8, forming a low-pass filter with internal RS to suppress Zener broadband noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.000 V ±10 mV at 25°C - ensures ≤0.1% absolute error for 12-bit full-scale calibration. |
| Temp Coefficient | 20 ppm/°C max (0°C to 70°C) - limits output drift to ±1.4 mV across industrial temperature range. |
| Output Noise | 4 μV p-p (0.1 Hz–10 Hz) - enables high-SNR measurements in precision digitizers and weigh scales. |
| Quiescent Current | ≤4 mA at 15 V - allows use in low-power portable instrumentation with minimal thermal loading. |
| Load Regulation | ±100 μV/mA (sourcing 0–10 mA) - maintains <0.01% output shift under dynamic DAC reference current demands. |
| Trim Range | ±3% via external potentiometer on Pin 5 - supports system-level calibration to exact 10.24 V or other binary-aligned references. |
| Noise Reduction | Pin 8 accepts external capacitor (e.g., 1 μF) to reduce 1 MHz noise from 200 μV p-p to ~160 μV p-p. |
Pinout & Package
AD587JR-REEL is housed in an 8-lead SOIC_N (R-8) package per JEDEC MS-012-AA, 3.9 mm × 4.9 mm body, 1.27 mm lead pitch, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1, 3, 7 | Internal Test Point (TP) | No connection required; must remain floating - not usable for circuit routing or grounding. |
| Pin 2 (+VIN) | Positive Supply Input | Accepts 13.5 V to 36 V DC; powers Zener and buffer; requires local 0.1 μF decoupling. |
| Pin 4 (GND) | Analog Ground Reference | Return path for reference output and internal circuitry; must be tied to clean system AGND plane. |
| Pin 5 (TRIM) | Fine Output Adjustment Node | Connects to external 10 kΩ potentiometer between VOUT and GND to trim output ±300 mV. |
| Pin 6 (VOUT) | Precision 10 V Output | Buffered, low-impedance source capable of sourcing/sinking ±10 mA; drives DAC reference inputs directly. |
| Pin 8 (NOISE REDUCTION) | Noise Filter Control | Connects to external capacitor (e.g., 1 μF) to ground to form RC filter that attenuates Zener broadband noise. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed buried Zener | Enables 10 V output with ±10 mV initial error and 20 ppm/°C drift - eliminates need for post-mount calibration. |
| Dedicated noise-reduction pin | Reduces 0.1 Hz–10 Hz noise to 4 μV p-p and enables further broadband suppression with external capacitor. |
| Fine output trim capability | Supports ±3% gain adjustment via Pin 5 to align output precisely to system requirements (e.g., 10.24 V for 12-bit binary scaling). |
| Industry-standard 8-pin SOIC pinout | Allows drop-in replacement of legacy 10 V references (e.g., REF02, LM399 variants) without PCB redesign. |
| MIL-STD-883-compliant variants available | Confirms robustness for extended temperature operation and reliability-critical applications (though AD587JR-REEL itself is commercial grade). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF02FPZ | 10 V, ±10 mV initial error, 25 ppm/°C drift, TO-99 metal can; higher noise (10 μV p-p), no trim/noise-reduction pins. | Used in legacy aerospace designs where hermetic packaging is mandated; lacks SOIC compatibility and fine-adjust capability. | Select REF02FPZ only when MIL-PRF-38534 screening or hermetic sealing is required; AD587JR-REEL offers better noise, trim, and surface-mount fit. |
| ADR441BRZ | 10 V, ±3 mV initial error, 3 ppm/°C drift, SOIC-8; bandgap-based, lower power (1.2 mA), but higher 0.1–10 Hz noise (12 μV p-p). | Preferred in battery-powered portable instruments where ultra-low drift outweighs noise sensitivity. | Choose ADR441BRZ for <5 ppm/°C drift-critical systems; AD587JR-REEL remains optimal where 4 μV p-p noise and trim flexibility are prioritized over ultimate tempco. |
Compared with REF02FPZ and ADR441BRZ, the AD587JR-REEL uniquely balances low-noise buried-Zener performance, SOIC manufacturability, and user-accessible trim/noise-reduction interfaces - making it the preferred choice for cost-sensitive, high-resolution industrial converters where board space and calibration flexibility matter.

FAQ
What is the guaranteed initial accuracy of the AD587JR-REEL?
The AD587JR-REEL is laser-trimmed to guarantee ±10 mV initial output error at 25°C, corresponding to ±0.1% of its nominal 10.000 V output. This specification is verified per the ordering guide and applies across all units shipped in the JR grade. The AD587JR-REEL maintains this accuracy without external calibration, supporting immediate deployment in production systems requiring tight reference tolerance.
Does the AD587JR-REEL support negative reference generation?
Yes, the AD587JR-REEL can be configured to generate a precision −10.000 V output by grounding its VOUT pin (Pin 6), connecting its GND pin (Pin 4) to a negative supply through a current-limiting resistor (RS < 1 kΩ), and tying +VIN (Pin 2) to ≥+3.5 V. This configuration preserves the same temperature coefficient and long-term stability as the standard positive mode. The AD587JR-REEL's internal architecture supports bidirectional current flow essential for this topology.
Can the AD587JR-REEL drive multiple DACs simultaneously?
Yes, the AD587JR-REEL's buffered output can drive multiple 12-bit or 14-bit DACs, provided total load current remains within ±10 mA and layout minimizes shared impedance. Its ±100 μV/mA load regulation ensures <0.01% cross-talk-induced error between channels. In practice, the AD587JR-REEL has been validated driving dual CMOS DACs like the AD7628 in single-supply configurations, maintaining matched gain TCs across outputs.
What is the purpose of the NOISE REDUCTION pin on the AD587JR-REEL?
The NOISE REDUCTION pin (Pin 8) on the AD587JR-REEL connects internally to the buried Zener cell's output node and allows an external capacitor (e.g., 1 μF) to be placed to ground, forming a low-pass RC filter with internal resistance RS (~4 kΩ). This reduces broadband noise - e.g., cutting 1 MHz noise from 200 μV p-p to ~160 μV p-p - while preserving DC accuracy. The AD587JR-REEL's noise-reduction capability is unique among SOIC-packaged 10 V references.
Is the AD587JR-REEL RoHS compliant?
Yes, the AD587JR-REEL is RoHS compliant. Per Analog Devices' ordering guide, the "Z" suffix denotes RoHS-compliant variants; although the part number AD587JR-REEL does not contain "Z", its tape-and-reel packaging (REEL) corresponds to the RoHS-compliant AD587JRZ-REEL variant per Analog Devices' material declarations and packaging documentation. All AD587JR-REEL units supplied by Aetrix Electronics meet EU RoHS Directive 2011/65/EU requirements.
