Product details
Overview
AD580SH/883B from Analog Devices is a 3-terminal, MIL-STD-883B-compliant, bandgap voltage reference delivering a precise 2.500 V ±25 mV output with 55 ppm/°C temperature coefficient over –55°C to +125°C, 1.5 mA max quiescent current, and TO-52 metal-can packaging - used as a stable reference for 12-bit DACs in aerospace data acquisition systems.
For engineers reviewing the AD580SH/883B datasheet, AD580SH/883B pinout, AD580SH/883B application, or AD580SH/883B equivalent, key selection criteria include military-grade thermal stability, hermetic package integrity, input voltage range (4.5 V–30 V), load regulation performance, and compatibility with single-supply 5 V logic systems.
Technical Context
The AD580SH/883B implements a laser-trimmed bandgap reference architecture using two bipolar transistors biased at different current densities to generate a temperature-compensated ΔVBE, summed with VBE to yield a stable 1.205 V extrapolated zero-TC point, then amplified to 2.5 V. Its three-terminal configuration requires no external components for regulation.
It operates across 4.5 V–30 V input while maintaining ≤10 mV load regulation (ΔI = 10 mA), ≤6 mV line regulation (7 V–30 V), and 8 µVp-p (0.1 Hz–10 Hz) low-frequency noise - enabling direct use in precision analog front-ends without post-regulation filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500 V ±25 mV - ensures ≤0.1% initial error for 12-bit converter full-scale calibration without user trimming. |
| Tempco | 55 ppm/°C - guarantees ≤1.375 mV total drift over –55°C to +125°C operating range for mission-critical instrumentation. |
| Quiescent Current | 1.0–1.5 mA - enables integration into low-power avionics subsystems powered from regulated 5 V rails. |
| Input Range | 4.5 V to 30 V - supports operation directly from unregulated aircraft bus voltages or standard logic supplies. |
| Long-Term Stability | 250 µV (25 µV/month) - maintains reference accuracy over multi-year deployments without recalibration. |
| Noise (0.1–10 Hz) | 8 µVp-p - minimizes quantization uncertainty in high-resolution ADC/DAC applications. |
| Load Regulation | 10 mV @ ΔI = 10 mA - sustains accuracy under dynamic load conditions typical of multiplexed sensor interfaces. |
Pinout & Package
AD580SH/883B is housed in a hermetic TO-52 metal-can package (H-03A), with bottom-view pin layout: Pin 1 = +E (input), Pin 2 = –E (ground), Pin 3 = EOUT (2.5 V output). Both EOUT pads must be connected to the output node per datasheet layout requirement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +E | Positive Input Supply | Accepts 4.5 V–30 V unregulated input; internal circuitry draws ≤1.5 mA to maintain regulation. |
| –E | Ground Reference | System ground return path; must be low-impedance to avoid noise coupling into reference output. |
| EOUT | Precision 2.5 V Output | Regulated, buffered output driving DAC references or comparator thresholds; requires dual-pad connection per layout spec. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables ±25 mV (±0.1%) initial tolerance without external calibration - critical for field-deployable test equipment. |
| Three-terminal operation | Eliminates need for external biasing components or feedback networks - reduces BOM count and PCB area in space-constrained modules. |
| MIL-STD-883B compliance | Validated screening including temperature cycling, mechanical shock, and hermeticity testing - required for flight-qualified hardware. |
| Wide input voltage range | Operates from 4.5 V up to 30 V - allows direct use with avionics 28 V buses or low-voltage CMOS logic rails without pre-regulation. |
| Low 0.1–10 Hz noise | 8 µVp-p noise floor - preserves effective resolution in 16+ bit data acquisition systems where 1 LSB ≈ 38 µV (2.5 V / 65536). |

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 | 2.5 V ±0.2%, 25 ppm/°C, SOIC-8, non-hermetic, not MIL-qualified | Commercial industrial control; lacks radiation tolerance and extended temp screening | Choose REF02FPZ only for cost-sensitive, non-military designs where TO-52 footprint and MIL-STD-883B are unnecessary. |
| LM399H | 6.95 V output, buried-Zener topology, 0.3 ppm/°C, TO-99, requires heater current | Ultra-stable lab metrology; incompatible pinout, higher power, different voltage level | LM399H suits ultra-low-drift bench instruments but cannot replace AD580SH/883B in 2.5 V, low-power, or space-constrained systems. |
Compared with REF02FPZ and LM399H, the AD580SH/883B uniquely combines hermetic TO-52 packaging, MIL-STD-883B compliance, 2.5 V output, and 1.5 mA quiescent current - making it irreplaceable in size-, power-, and reliability-constrained defense electronics.

FAQ
What is the operating temperature range for AD580SH/883B?
The AD580SH/883B is specified for operation from –55°C to +125°C, with storage range extending to –65°C to +175°C. Its 55 ppm/°C temperature coefficient ensures ≤1.375 mV total output variation across this full range, validated per MIL-STD-883B Method 1010.8 temperature cycling.
Does AD580SH/883B require external capacitors for stability?
No, the AD580SH/883B is internally compensated and operates stably without external capacitors. Its three-terminal architecture and buffered output allow direct connection to ADC reference inputs or op-amp non-inverting terminals, as confirmed in Figure 6 and Figure 12 of the Rev. B datasheet.
Is AD580SH/883B compatible with 5 V-only systems?
Yes, AD580SH/883B functions reliably with 5 V input (minimum 4.5 V), drawing ≤1.5 mA quiescent current. This enables direct use in 5 V logic-powered systems like the AD7542 DAC interface shown in Figure 12, eliminating need for separate ±15 V supplies.
What is the long-term stability specification for AD580SH/883B?
The AD580SH/883B guarantees 250 µV maximum long-term output drift, with 25 µV/month typical. This specification is measured under controlled conditions per MIL-STD-883B Method 1008 and supports calibration intervals exceeding 24 months in deployed systems.
How does the TO-52 package of AD580SH/883B differ from plastic alternatives?
The TO-52 metal-can package provides hermetic sealing, superior thermal conductivity (100°C/W junction-to-case), and immunity to moisture-induced parameter shift - essential for high-reliability aerospace applications where plastic-packaged references like REF02FPZ would fail qualification testing.
