AD976ASD/883

The AD976ASD/883 is a high-reliability 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices, providing 200 kSPS conversion throughput in a hermetically sealed CDIP package. As part of the AD976/AD976A family, this monolithic device operates from a single 5 V supply, integrates an internal reference, and offers a full parallel data interface compatible with a wide range of digital hosts. The SAR architecture balances fast acquisition with low power dissipation, while precision thin-film resistor design delivers the monotonicity, low integral nonlinearity, and high signal-to-noise ratio expected from this product family, making it suitable for precision sampling of dynamic signals and quasi-static transducer inputs alike.

Typical deployment scenarios include military avionics, radar and sonar processing, industrial automated test equipment, and high-reliability instrumentation where full MIL-STD-883 screening is contractually required. The /883 suffix guarantees operation over the military temperature range and compliance with rigorous environmental, mechanical, and burn-in test methods, while the ceramic DIP construction ensures long-term stability in shock- and moisture-prone environments. From a procurement perspective, this device occupies a mature product lifecycle position; design and supply-chain teams should verify ongoing production status and lead-times with authorized distribution. Its qualified MIL-grade heritage and hermetic packaging make the AD976ASD/883 a practical choice for legacy defense platforms or extended-duration programs demanding certified traceability and form, fit, and function consistency.
