Product details
Overview
AD589TH/883B from Analog Devices is a 2-terminal, MIL-STD-883-compliant, temperature-compensated bandgap voltage reference delivering a precise 1.23 V output over –55°C to +125°C, with 50 ppm/°C max temperature coefficient, 0.6 Ω dynamic output impedance, and operation down to 50 µA input current. It serves as a stable shunt reference in high-reliability aerospace and military power monitoring and data acquisition systems.
For engineers reviewing the AD589TH/883B datasheet, AD589TH/883B pinout, AD589TH/883B application, or AD589TH/883B equivalent, key selection criteria include its hermetic metal-can (H-02) packaging, wide temperature range compliance, low-noise 5 µV RMS (10 Hz–10 kHz), and ability to operate as floating, positive, or negative reference without external compensation.
Technical Context
The AD589TH/883B implements a precision bandgap reference topology using Analog Devices' bipolar process and thin-film trimming, achieving stable 1.23 V output via matched on-chip components with tight thermal tracking. Its 2-terminal shunt architecture eliminates need for series pass elements or external feedback networks.
It operates across 50 µA–5 mA input current with <5 mV output variation, 25 µs turn-on settling to 0.1%, and intrinsic low output impedance (0.6 Ω typ) that maintains accuracy under dynamic load changes - all without frequency compensation or external capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.235 V nominal at 25°C; ±25 mV tolerance (1.200 V–1.250 V) ensures compatibility with 12-bit ADC reference inputs. |
| Temp Coefficient | 50 ppm/°C max (–55°C to +125°C); guarantees ≤±6.25 mV total drift over full range for precision sensor biasing. |
| Dynamic Output Impedance | 0.6 Ω typical; enables stable regulation even with fast load transients up to 5 mA, eliminating need for local bypass caps. |
| Operating Current Range | 50 µA to 5 mA; supports ultra-low-power battery operation while retaining full accuracy at higher currents. |
| RMS Noise (10 Hz–10 kHz) | 5 µV RMS; minimizes quantization error in high-resolution ADCs such as 12-bit integrating types (e.g., AD7109). |
| Turn-On Settling Time | 25 µs to 0.1%; allows rapid power cycling in intermittent-sampling instrumentation without calibration delay. |
Pinout & Package
Metal Can (H-02) hermetic package: 2-pin TO-51-style header with axial leads; pin 1 = cathode (–V), pin 2 = anode (+V); compatible with standard H-02 socket mounting and vacuum-sealed PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Reference output node / current sink | Connected to system ground or negative rail when used as positive reference; defines 1.23 V potential relative to anode. |
| Pin 2 (Anode) | Input current terminal / reference return | Accepts regulated input current; polarity reversal enables negative reference configuration (anode grounded, cathode at –1.23 V). |
Key Features
| Feature | Design Value |
|---|---|
| 2-Terminal Shunt Operation | Eliminates need for external resistors or op-amps in basic reference configurations - reduces BOM count and layout area. |
| No Frequency Compensation Required | Stable under all capacitive loads from 0 pF to ≥1 µF; avoids instability risks common in Zener-based references. |
| Floating, Positive, or Negative Reference Modes | Enables single device to serve multiple topologies: grounded-cathode (positive ref), grounded-anode (negative ref), or isolated (floating) biasing. |
| MIL-STD-883B Compliance | Qualified per Method 5005 for screening, burn-in, and environmental stress testing - meets Class B requirements for space-grade reliability. |
| Low Power Dissipation | 60 µW at 50 µA; extends battery life in portable telemetry and remote sensor nodes without sacrificing voltage stability. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-terminal shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF02CH/883B | 2.5 V output, 25 ppm/°C TC, SOIC-8 package; requires external resistor for current setting in shunt mode. | Higher output voltage limits use in 1.2 V–1.5 V ADC systems; SOIC packaging lacks hermeticity for extended temperature mission profiles. | Select only if 2.5 V reference level and surface-mount assembly are mandatory; verify thermal derating for >105°C ambient. |
| LM385BH-1.2/883 | 1.235 V output, 100 ppm/°C TC (–55°C to +125°C), same H-02 package; higher TC and 10 Ω output impedance. | Less stable over temperature and more sensitive to load variation; unsuitable for high-accuracy 12-bit+ systems requiring <±3 mV total error. | Acceptable for cost-sensitive legacy designs where 100 ppm/°C drift is tolerable; avoid in new aerospace/military programs targeting Class B reliability. |
Compared with REF02CH/883B and LM385BH-1.2/883, the AD589TH/883B uniquely combines 1.23 V output, 50 ppm/°C TC, 0.6 Ω impedance, and MIL-STD-883B-qualified H-02 packaging - making it the only drop-in solution for high-stability, low-voltage, wide-temperature shunt referencing in safety-critical platforms.

FAQ
What is the operating temperature range of the AD589TH/883B?
The AD589TH/883B is rated for continuous operation from –55°C to +125°C. This full military temperature range is verified per MIL-STD-883B test methods, including thermal cycling and high-temperature storage, ensuring performance stability in harsh aerospace and defense environments where the AD589TH/883B is deployed.
Is the AD589TH/883B pin-compatible with other AD589 variants?
Yes - all AD589 variants in the H-02 metal can package, including AD589TH/883B, share identical 2-pin TO-51 pinout (cathode/anode). However, electrical specifications differ: AD589TH/883B has 50 ppm/°C TC and –55°C to +125°C rating, unlike AD589MH (10 ppm/°C, 0°C to +70°C) or AD589JH (100 ppm/°C, 0°C to +70°C). The AD589TH/883B must be selected specifically for wide-temp, medium-TC applications.
Does the AD589TH/883B require external capacitors for stability?
No - the AD589TH/883B does not require external frequency compensation. Its internal design provides inherent stability across capacitive loads from 0 pF to ≥1 µF. For ultralow-noise applications, a minimum 1000 pF shunt capacitor is recommended, but it is not required for basic regulation. This simplifies layout and improves reliability compared to Zener-based references needing careful compensation.
Can the AD589TH/883B be used as a negative voltage reference?
Yes - the AD589TH/883B supports three configurations: grounded-cathode (positive 1.23 V), grounded-anode (negative 1.23 V), and floating. When the anode is tied to system ground and the cathode supplies the reference node, the AD589TH/883B delivers a stable –1.23 V output ideal for CMOS DACs like the AD7533. No polarity-reversal diodes or additional components are needed.
What is the maximum input current rating for the AD589TH/883B?
The absolute maximum input current for the AD589TH/883B is 10 mA, per its Absolute Maximum Ratings table. However, optimal performance is achieved below 500 µA; operation above this level increases self-heating and may elevate temperature-induced drift. The AD589TH/883B is fully specified from 50 µA to 5 mA, with <5 mV output variation across that range - making 5 mA the practical upper limit for precision use.
