Product details
Overview
AD584SH/883B from Analog Devices is a MIL-STD-883-compliant, 8-pin TO-99 hermetic metal-can precision voltage reference IC with pin-programmable outputs of 10.000 V, 7.500 V, 5.000 V, or 2.500 V; laser-trimmed initial accuracy of ±15 mV (5 V output), max 30 ppm/°C tempco over −55°C to +125°C, and 10 mA output drive capability. It serves as a stable reference for high-resolution ADCs, DACs, and calibration systems in aerospace and defense instrumentation.
For engineers reviewing the AD584SH/883B datasheet, AD584SH/883B pinout, AD584SH/883B application, or AD584SH/883B equivalent, this page delivers verified specifications, TO-99 package mapping, strobe-controlled on/off operation, 2-terminal negative reference capability, and real-world selection guidance against qualified alternatives - all grounded in Analog Devices' Rev. C datasheet and MIL-STD-883B compliance documentation.
Technical Context
The AD584SH/883B implements a bandgap-based 1.215 V reference core with a programmable resistor ladder and buffered output amplifier, enabling four discrete output voltages without external components. Its internal architecture supports both sourcing and sinking up to 5 mA across temperature while maintaining <50 µVp-p (0.1 Hz–10 Hz) noise and 200 µs turn-on settling to 0.1%.
Strobe terminal (Pin 5) enables TTL-compatible on/off control, reducing quiescent current from 750 µA (active) to ~100 µA (off). The device operates from 4.5 V to 30 V input and supports 2-terminal Zener-mode operation for −5 V, −7.5 V, or −10 V negative references when COMMON is used as output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Pin-selectable 10.000 V / 7.500 V / 5.000 V / 2.500 V - no external resistors needed for standard outputs. |
| Initial Accuracy (5 V) | ±15 mV max - ensures ≤0.3% full-scale error at 25°C for 5 V mode, critical for 12-bit DAC referencing. |
| Tempco (−55°C to +125°C) | 30 ppm/°C max - guarantees ≤±3.75 mV drift over full military range, validated per MIL-STD-883B test method 1010.8. |
| Output Drive | ±5 mA over temperature - sustains stable regulation under load while sourcing or sinking, enabling direct interface to op-amp inputs or ADC reference pins. |
| Quiescent Current | ≤1.0 mA - allows low-power system design; drops to ~100 µA in strobe-off state for battery-backed subsystems. |
| Turn-On Settling | 200 µs to 0.1% - supports fast-cycling measurement systems requiring rapid reference stabilization after power-up. |
| Noise (0.1–10 Hz) | 50 µVp-p - low enough to avoid degrading ENOB in 14-bit successive-approximation ADCs. |
Pinout & Package
AD584SH/883B is housed in an 8-pin hermetically sealed TO-99 metal can (package option H-08), with tab connected to Pin 4 (COMMON). This package provides superior thermal stability and EMI shielding for high-reliability military/aerospace applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output (VOUT) | Buffered, programmable reference voltage node - connects to ADC/DAC REF pin or op-amp noninverting input. |
| 2 | 5.0 V Tap | Internal resistor ladder node - tied to Pin 1 for 5 V output; used with external buffers for multi-voltage generation. |
| 3 | 2.5 V Tap | Internal resistor ladder node - tied to Pin 1 for 2.5 V output; also used in trimming configurations per Figure 4. |
| 4 | COMMON | Reference ground and heatsink tab - must be connected to system analog ground; tab is electrically tied to this pin. |
| 5 | STROBE | Active-low enable - pulled ≤200 mV to disable output and reduce current to ~100 µA; driven by open-collector TTL gate. |
| 6 | VBG | Bandgap reference node - internal 1.215 V source; used with external capacitor (Pin 7) for noise filtering. |
| 7 | CAP | Noise filter terminal - connect 0.01–0.1 µF capacitor to Pin 6 (VBG) to reduce wideband noise at cost of increased settling time. |
| 8 | V+ | Positive supply input - accepts 4.5 V to 30 V; requires ≥2.5 V headroom above selected output for regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Four-pin-programmable outputs | Eliminates need for multiple fixed references - one AD584SH/883B replaces discrete 2.5 V, 5 V, 7.5 V, and 10 V parts in test equipment BOMs. |
| Laser-trimmed tempco & accuracy | Guarantees ≤30 ppm/°C drift and ±15 mV initial error over −55°C to +125°C without calibration - reduces post-manufacture trimming effort. |
| Strobe-controlled on/off | Enables power-gating of reference circuitry in standby mode, cutting supply current by >90% while preserving fast wake-up (<200 µs). |
| 2-terminal negative reference mode | Supports precision −5 V, −7.5 V, or −10 V generation by connecting V+ and VOUT - simplifies bipolar supply designs without extra regulators. |
| Source/sink output capability | Handles ±5 mA loads across temperature - accommodates op-amp bias currents and reference input leakage without external buffering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5025MDREP | Fixed 2.5 V output; 3 ppm/°C max tempco; SOIC-8 package; not MIL-qualified. | Lower drift but no pin-programmability or strobe; unsuitable for multi-voltage or power-gated systems. | Select REF5025MDREP only if fixed 2.5 V and ultra-low tempco outweigh need for programmability and military screening. |
| MAX6126AASA+ | Fixed 5.0 V output; 12 ppm/°C max tempco; 8-pin SOIC; AEC-Q200 qualified, not MIL-STD-883B. | Automotive-grade reliability but lacks strobe, negative reference mode, and hermetic packaging. | Choose MAX6126AASA+ for automotive ECUs needing 5 V reference with moderate tempco, but not for defense/aerospace deployments. |
Compared with REF5025MDREP and MAX6126AASA+, the AD584SH/883B uniquely combines military-grade screening, pin-selectable outputs, strobe control, and 2-terminal negative reference capability - making it irreplaceable in multi-function, power-constrained, and extreme-environment systems where flexibility and ruggedness are mandatory.

FAQ
What is the guaranteed temperature coefficient of AD584SH/883B over its full operating range?
The AD584SH/883B has a maximum temperature coefficient of 30 ppm/°C over the −55°C to +125°C operating range, as specified in Table 2 of the Rev. C datasheet and verified under MIL-STD-883B test method 1010.8. This applies to all four output voltages (2.5 V, 5.0 V, 7.5 V, and 10.0 V) and ensures predictable drift behavior in extreme-environment deployments.
Can AD584SH/883B be used as a negative voltage reference, and how is it configured?
Yes, AD584SH/883B supports 2-terminal Zener-mode operation for negative references. To generate −5 V, connect V+ (Pin 8) and VOUT (Pin 1) together to ground, route COMMON (Pin 4) through a current-limiting resistor to the negative supply rail, and take the output from COMMON. This configuration delivers −5 V with typical 2 mV increase over 3-terminal mode and maintains the same long-term stability.
Does AD584SH/883B require external capacitors for stability, and what is the role of the CAP pin?
The CAP pin (Pin 7) is intended for optional noise filtering: connecting a 0.01 µF to 0.1 µF capacitor between CAP and VBG (Pin 6) reduces wideband and feedthrough noise, lowering total RMS noise per Figure 10. However, this increases turn-on settling time, so the capacitor should only be used where noise performance outweighs speed requirements - no capacitor is required for basic regulation.
What is the function of the STROBE pin on AD584SH/883B, and what drive capability is required?
The STROBE pin (Pin 5) is an active-low enable that forces the output to zero and reduces quiescent current to ~100 µA when pulled ≤200 mV. Its driver must sink ≥500 µA continuously and tolerate up to AD584SH/883B's output voltage plus 1 V. A standard open-collector TTL gate or NPN transistor switch (e.g., 2N2222 with 10 kΩ pull-up) meets this requirement per Figure 11.
Is AD584SH/883B pin-compatible with other AD584 variants like AD584KH or AD584TH?
Yes, all AD584 variants - including AD584SH/883B, AD584KH, and AD584TH - share identical 8-pin TO-99 pinouts and electrical functionality. Differences lie solely in temperature range, initial accuracy, tempco, and qualification level (e.g., MIL-STD-883B screening for AD584SH/883B). No PCB changes are required when substituting within the same package type.
