AD586SQ/883B

The AD586SQ/883B from Analog Devices is a precision 5.0 V buried Zener voltage reference, supplied as a MIL-STD-883B screened component in a hermetic ceramic pin grid array (CPGA) package. This device delivers a highly stable 5.000 V output with very low temperature drift—typically as low as 5 ppm/°C for the SQ grade—and low output noise, enabling accurate performance in high-resolution measurement and calibration systems. The buried Zener architecture provides excellent long-term stability and low aging rates, while the CPGA package ensures robust environmental protection and thermal resilience in harsh operating conditions.

Typical applications include precision data acquisition, military avionics, high-reliability instrumentation, and aerospace guidance systems where a trustworthy voltage reference is critical for analog-to-digital conversion and signal conditioning. The /883B suffix denotes full compliance with MIL-STD-883 Class B screening, encompassing temperature cycling, constant acceleration, burn-in, and hermeticity testing, making this part suitable for long-life defense and space-qualified platforms with stringent change-control requirements. Procurement considerations include verifying authorized distribution chain-of-custody to avoid counterfeits, as well as evaluating extended lead times and minimum order quantities associated with this specialized screening. Designers should confirm ongoing production support and lifecycle status when planning integration into sustainment-driven military or high-reliability industrial programs.
