Product details
Overview
AD587KRZ-REEL from Analog Devices is a precision 10 V monolithic voltage reference IC using a buried Zener diode architecture, laser-trimmed for ±5 mV initial accuracy and 10 ppm/°C max temperature coefficient over 0°C to 70°C. It delivers 4 μV p-p (0.1–10 Hz) output noise, supports up to 10 mA load current, and features dedicated noise-reduction and fine-trim pins - ideal for high-resolution DAC/ADC reference applications in test equipment and data acquisition systems.
For engineers reviewing the AD587KRZ-REEL datasheet, AD587KRZ-REEL pinout, AD587KRZ-REEL application, or AD587KRZ-REEL equivalent, key selection criteria include its SOIC_N-8 package compatibility, guaranteed 10 ppm/°C drift over commercial temperature range, low quiescent current (≤4 mA), and noise-reduction capacitor interface for sub-μV noise optimization in metrology-grade signal chains.
Technical Context
The AD587KRZ-REEL integrates a proprietary ion-implanted buried Zener diode with laser-trimmed thin-film resistors and a precision buffer amplifier. Its architecture enables lower long-term drift (±15 ppm/1000 hr) and lower 0.1–10 Hz noise than bandgap references, while maintaining industry-standard 8-lead SOIC pinout for drop-in replacement of legacy 10 V references.
It supports dual-mode operation: standard +10 V output and configurable −10 V output via ground-pin sourcing. The TRIM pin allows ±3% gain adjustment (±300 mV offset), and the NOISE REDUCTION pin enables external RC filtering to reduce broadband noise by ~25% with a 1 μF capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.000 V ±5 mV at 25°C - ensures ≤0.05% absolute error for 12-bit+ converter full-scale calibration. |
| Temp Coefficient | 10 ppm/°C max (0°C to 70°C) - limits total error to ≤700 μV across commercial temperature range. |
| Output Noise | 4 μV p-p (0.1–10 Hz) - enables <16-bit ENOB in precision ADCs without external filtering. |
| Quiescent Current | ≤4 mA - allows use in low-power portable instrumentation with 15 V supply. |
| Load Regulation | ±100 μV/mA (sourcing) - maintains stability under dynamic DAC reference current loads. |
| Long-Term Stability | ±15 ppm/1000 hr - reduces recalibration frequency in automated test systems. |
| Short-Circuit Protection | Indefinite short-to-ground, momentary short-to-VIN - enhances field reliability in mixed-signal PCBs. |
Pinout & Package
AD587KRZ-REEL is housed in an 8-lead SOIC_N (R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch, 5.00 mm × 4.00 mm body, and 1.75 mm height - compatible with standard surface-mount reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7 | TP (Test Point) | No connection - internal factory test nodes; must remain floating in circuit. |
| 2 | +VIN | Main input supply (13.5–36 V); powers Zener and buffer; requires local 0.1 μF decoupling. |
| 4 | GND | Analog ground reference; must be star-connected to minimize ground bounce in mixed-signal systems. |
| 5 | TRIM | Fine-adjustment node; ±3% gain control via external 10 kΩ potentiometer for system-level calibration. |
| 6 | VOUT | Stable 10 V output; capable of sourcing/sinking ±10 mA; requires low-ESR ceramic output capacitor if driving capacitive loads. |
| 8 | NOISE REDUCTION | Connects to Zener bias node; adding 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 10 ppm/°C drift and ±5 mV initial accuracy without external compensation components. |
| Dedicated noise-reduction pin | Allows external capacitor filtering to suppress Zener-generated broadband noise without affecting DC accuracy. |
| Fine-trim capability (±3%) | Permits exact 10.000 V or binary-aligned 10.24 V output matching system master reference standards. |
| Industry-standard SOIC-8 pinout | Enables direct upgrade of legacy 10 V references (e.g., REF02, LM399) without PCB layout changes. |
| −10 V negative reference mode | Configurable via ground-pin sourcing (Pin 4), retaining same tempco and stability as positive mode. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR441BRZ | 2.5 V output, 3 ppm/°C drift, 1.8 μV p-p noise - lower noise but fixed 2.5 V, not 10 V. | Requires external gain stage for 10 V DAC reference; better for low-voltage, ultra-low-noise systems. | Select ADR441BRZ only when system architecture permits 2.5 V reference with amplification and demands <2 μV p-p noise. |
| REF5010AIDR | 10 V output, 3 ppm/°C drift, 5 μV p-p noise, 10 mA drive - tighter drift but higher noise and cost. | Pinout incompatible (SOIC-8 vs. SOIC-8 with different pin functions); requires layout revision. | Choose REF5010AIDR only when <3 ppm/°C drift is mandatory and board redesign is acceptable. |
Compared with ADR441BRZ and REF5010AIDR, the AD587KRZ-REEL uniquely balances 10 V output, SOIC-8 pin compatibility, 10 ppm/°C drift, and 4 μV p-p noise - making it the optimal drop-in upgrade for legacy 10 V reference designs where PCB change is prohibited and moderate drift tolerance exists.

FAQ
What is the maximum input voltage rating for AD587KRZ-REEL?
The AD587KRZ-REEL has an absolute maximum +VIN rating of 36 V. Operation is specified from 13.5 V to 36 V, with typical performance characterized at 15 V. Exceeding 36 V risks permanent damage per Absolute Maximum Ratings table in Rev. H datasheet. Always include input transient protection in industrial environments where supply rails may experience surges.
Can AD587KRZ-REEL be used to generate a negative 10 V reference?
Yes, the AD587KRZ-REEL can configure a precision −10.000 V output by grounding the VOUT pin (Pin 6), connecting +VIN (Pin 2) to ≥+3.5 V, and routing the GND pin (Pin 4) through a resistor (RS <1 kΩ) to a −15 V rail. This preserves the same 10 ppm/°C drift and ±15 ppm/1000 hr stability as the positive configuration, as confirmed in Figure 17 and Applications Information section.
Does AD587KRZ-REEL require external capacitors for stability?
The AD587KRZ-REEL operates stably without external capacitors under resistive loads. However, a 0.1 μF ceramic capacitor between +VIN and GND is recommended for supply decoupling, and a 1 μF capacitor on the NOISE REDUCTION pin (Pin 8) is required to achieve the specified 160 μV p-p broadband noise reduction. Output capacitance is optional but advised for capacitive loads >100 pF.
What is the turn-on settling time of AD587KRZ-REEL?
With no external noise-reduction capacitor, the AD587KRZ-REEL achieves 0.01% settling in ≈60 μs after power application. When a 1 μF capacitor is placed on Pin 8, turn-on time extends to ≈400 ms due to added RC time constant loading the internal Zener current source - a trade-off explicitly documented in Figure 9 and Turn-On Time section of Rev. H datasheet.
Is AD587KRZ-REEL RoHS compliant?
Yes, the "Z" suffix in AD587KRZ-REEL denotes RoHS compliance per Analog Devices' ordering guide (Page 12, Rev. H). It uses lead-free terminations and meets EU Directive 2011/65/EU requirements, verified through material declarations and manufacturing process controls.
