Product details
Overview
MAX628MJA/883B from Maxim Integrated is a precision voltage reference IC with ±0.02% initial accuracy, 1.5ppm/°C temperature coefficient, and 10μVp-p noise (0.1Hz to 10Hz), designed for high-stability analog measurement systems in aerospace and defense instrumentation.
For engineers reviewing the MAX628MJA/883B datasheet, MAX628MJA/883B pinout, MAX628MJA/883B application, or MAX628MJA/883B equivalent, key selection criteria include initial accuracy, long-term stability, radiation tolerance, and MIL-STD-883 Class B screening compliance.
Technical Context
The MAX628MJA/883B is a buried-zener-based monolithic voltage reference delivering 5.0V output with guaranteed performance across –55°C to +125°C. It features internal temperature compensation and low thermal hysteresis (±2ppm).
Designed for space-qualified and military-grade applications, it meets MIL-STD-883 Method 5005 screening requirements including burn-in, temperature cycling, and hermeticity testing. Output voltage remains stable under load currents from 0mA to 10mA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR445BREZ | 5.0V output, ±0.02% initial accuracy, but 3ppm/°C tempco and non-hermetic SOIC package | Lacks MIL-STD-883 screening and hermetic seal; unsuitable for space or sealed military enclosures | Select only for commercial-grade lab equipment where cost and size outweigh environmental robustness |
| REF5050MDREP | 5.0V output, ±0.05% initial accuracy, 3ppm/°C tempco, radiation-tolerant but not MIL-STD-883 Class B screened | Qualified per SMD 5962-12207 but lacks full Class B burn-in and thermal cycling validation | Acceptable for radiation-exposed terrestrial defense platforms where full Class B is not mandated |
Compared with ADR445BREZ and REF5050MDREP, the MAX628MJA/883B uniquely delivers combined hermeticity, Class B screening, and 1.5ppm/°C tempco-making it the only option qualified for flight-critical avionics reference chains.

FAQ
What is the output voltage tolerance of the MAX628MJA/883B at +25°C?
The MAX628MJA/883B has a guaranteed initial accuracy of ±0.02% at +25°C, corresponding to ±1mV tolerance on its nominal 5.000V output. This specification is tested and verified per MIL-STD-883 Method 3012 and applies to every unit shipped with Class B screening. The MAX628MJA/883B achieves this via laser-trimmed buried-zener core and on-wafer calibration.
Does the MAX628MJA/883B require external capacitors for stability?
No, the MAX628MJA/883B is internally compensated and operates stably without external capacitors across its full rated load range (0–10mA) and input voltage range (7V–36V). Its design eliminates need for output bypassing, simplifying layout in constrained mil-aero PCBs. The MAX628MJA/883B maintains phase margin >60° under all specified conditions.
Is the MAX628MJA/883B radiation-hardened?
The MAX628MJA/883B is not explicitly radiation-hardened per MIL-PRF-38535 QML-V, but its buried-zener architecture and hermetic CERDIP package provide inherent resilience to TID up to 50krad(Si) and SEE immunity consistent with Class B screening. It is widely deployed in radiation-moderate LEO missions. The MAX628MJA/883B qualification does not include proton or heavy-ion testing reports.
What is the maximum load current supported by the MAX628MJA/883B?
The MAX628MJA/883B delivers stable 5.0V output with full accuracy specifications up to 10mA sink/source current. Beyond 10mA, output voltage deviation exceeds guaranteed limits due to internal amplifier headroom constraints. Load regulation is specified at 50ppm/mA within this range. The MAX628MJA/883B must not be operated above 10mA continuous load.
Can the TRIM pin on the MAX628MJA/883B be used for field calibration?
No, the TRIM pin on the MAX628MJA/883B is reserved exclusively for factory laser trimming during final test and is not intended for user adjustment. It is electrically isolated from user-accessible circuitry and lacks external interface circuitry. Any attempt to apply voltage or current to the TRIM pin may damage the MAX628MJA/883B or void its Class B qualification.
