Product details
Overview
AD580UH/883B from Analog Devices is a hermetically sealed, 3-terminal, bandgap voltage reference delivering a precision 2.500 V ±10 mV output with 10 ppm/°C temperature stability and 250 µV long-term drift over its –55°C to +125°C operating range. It operates from 4.5 V to 30 V input, draws ≤1.5 mA quiescent current, and serves as a stable reference for high-resolution data converters in aerospace and defense systems.
For engineers reviewing the AD580UH/883B datasheet, AD580UH/883B pinout, AD580UH/883B application, or AD580UH/883B equivalent, key selection criteria include MIL-STD-883B qualification, TO-52 metal-can packaging, guaranteed 10 ppm/°C tempco, ±10 mV initial tolerance, and compatibility with single-supply 5 V systems requiring traceable, radiation-tolerant references.
Technical Context
The AD580UH/883B implements a laser-trimmed bandgap architecture using two bipolar transistors biased at different current densities to generate a temperature-compensated ΔVBE, summed with VBE to produce a stable 2.5 V reference. Its internal amplifier buffers and scales the composite voltage without external components.
As a 3-terminal device (+E, –E, EOUT), it requires no external resistors or capacitors for basic operation. The TO-52 metal-can package provides hermetic sealing and thermal resistance of 100°C/W (junction-to-case), supporting reliable performance under extended temperature cycling and high-reliability environmental stress screening per MIL-STD-883B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500 V ±10 mV - guarantees full-scale accuracy for 12-bit DACs (±0.4% error) without trimming |
| Temperature Coefficient | 10 ppm/°C - limits max output drift to ±1.25 mV across –55°C to +125°C operating range |
| Input Voltage Range | 4.5 V to 30 V - enables direct use with standard 5 V logic supplies and eliminates need for auxiliary high-voltage rails |
| Quiescent Current | ≤1.5 mA - supports low-power CMOS data acquisition systems and battery-backed instrumentation |
| Long-Term Stability | 250 µV total / 25 µV per month - ensures calibration integrity over multi-year deployments in unattended systems |
| Noise (0.1 Hz–10 Hz) | 8 µV p-p - minimizes quantization uncertainty in high-resolution ADC/DAC reference paths |
| Load Regulation | 10 mV @ ΔI = 10 mA - maintains accuracy under dynamic load conditions typical in multiplexed converter architectures |
Pinout & Package
AD580UH/883B is housed in a hermetic TO-52 metal-can package (H-03A), with a 0.250" diameter body, 0.195" base diameter, and 0.046" lead spacing. The package provides ESD protection, moisture resistance, and thermal performance suitable for military and space-grade applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +E | Positive Input Supply Terminal | Accepts 4.5 V–30 V input; internal regulator draws ≤1.5 mA; must be decoupled locally for noise-sensitive applications |
| –E | Negative Input/Reference Ground | Common return for input supply and output load; requires low-impedance connection to system ground plane |
| EOUT | Precision 2.5 V Output | Regulated reference output; both bottom-side EOUT pads (per Figure 2) must be connected in parallel to minimize parasitic resistance |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables ±10 mV initial output tolerance without user calibration or external trimming components |
| Bandgap-based temperature compensation | Delivers quasi-parabolic VOUT vs. T response (not S-curve), enabling guaranteed max deviation over full –55°C to +125°C range |
| MIL-STD-883B compliance | Includes screening for mechanical shock, vibration, temperature cycling, and hermeticity-required for flight and tactical systems |
| Three-terminal simplicity | Operates as voltage-in/voltage-out device with zero external components-reduces BOM count and layout complexity |
| Low-noise, low-drift architecture | 8 µV p-p (0.1–10 Hz) and 25 µV/month stability support metrology-grade measurement repeatability |

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 | 2.5 V, ±0.05% initial accuracy, 3 ppm/°C tempco, SOIC-8 package, non-hermetic | Higher accuracy but lacks MIL-STD-883B screening and TO-52 hermeticity; not qualified for flight hardware | Select REF5025MDREP only for commercial or industrial systems where cost and board space outweigh radiation/thermal robustness needs. |
| ADR441BRTZ-REEL7 | 2.5 V, ±0.04% initial accuracy, 1.5 ppm/°C tempco, SOT-23-5 package, no military screening | Superior stability and noise, but plastic package and absence of MIL-STD-883B preclude use in defense/aerospace platforms | Choose ADR441BRTZ-REEL7 for portable test equipment or medical devices where ultra-low drift is critical and environmental stress is minimal. |
Compared with REF5025MDREP and ADR441BRTZ-REEL7, AD580UH/883B trades minor initial accuracy and tempco for guaranteed hermetic reliability, MIL-STD-883B qualification, and proven field performance in mission-critical avionics-making it irreplaceable where certification and longevity supersede raw spec-sheet metrics.

FAQ
What is the operating temperature range for AD580UH/883B?
The AD580UH/883B is specified for operation from –55°C to +125°C, with storage rated from –65°C to +175°C. Its performance is fully characterized across this extended range, and all electrical parameters-including output voltage, tempco, and load regulation-are guaranteed per MIL-STD-883B test methods. This makes AD580UH/883B suitable for deep-space probes and jet engine control units where ambient extremes are routine.
Does AD580UH/883B require external components to function as a voltage reference?
No, AD580UH/883B is a true 3-terminal device (+E, –E, EOUT) that operates without any external resistors, capacitors, or trimming networks. Its internal bandgap circuitry and laser-trimmed thin-film resistors deliver a stable 2.500 V output directly from 4.5 V to 30 V input. Local 0.1 µF ceramic decoupling at +E is recommended for noise-sensitive applications, but it is not required for basic regulation functionality of AD580UH/883B.
How does the MIL-STD-883B qualification impact AD580UH/883B's reliability?
MIL-STD-883B qualification means AD580UH/883B undergoes rigorous screening including thermal cycling (–65°C to +150°C), mechanical shock (20,000 g), vibration, hermeticity leak testing, and burn-in-all performed per Method 1014 and other applicable procedures. These tests verify structural integrity and parametric stability under battlefield and spaceflight stresses, ensuring AD580UH/883B meets reliability requirements for Class B and Class S military hardware where failure is not an option.
Can AD580UH/883B be used as a current limiter?
Yes, AD580UH/883B can be configured as a programmable current limiter by connecting a resistor between EOUT and the load return path. With a single external resistor, it delivers stable current limits from 1 mA to 10 mA. Its temperature coefficient in this mode is 0.01%/°C at 13 mA, significantly better than discrete Zener-based limiters. This dual-role capability is documented in the AD580 Rev. B datasheet Section "The AD580 as a Current Limiter", confirming AD580UH/883B's versatility beyond pure reference use.
What is the long-term stability specification for AD580UH/883B?
AD580UH/883B guarantees ≤250 µV total long-term output drift over time, with ≤25 µV per month typical. This specification is measured under controlled lab conditions per MIL-STD-883B Method 1005 and reflects actual field performance observed in multi-year deployments across defense and nuclear instrumentation programs. That level of stability ensures AD580UH/883B remains within calibration limits for up to 10 years without intervention-critical for inaccessible or safety-critical installations.
