AD674BBD

The AD674BBD is a complete 12-bit successive approximation analog-to-digital converter (ADC) from Analog Devices, integrating a precision voltage reference, clock, and bus interface to deliver standalone conversion capability. The device converts an analog input to a 12-bit digital output with fast conversion speed typical of the AD674B family, requiring no external components beyond power supply decoupling. Housed in a hermetically sealed ceramic dual-in-line package (CDIP), it provides robust electrical performance across extended temperature ranges and high-vibration environments, minimizing board space and component count in embedded data acquisition paths.

Typical system roles include precision industrial instrumentation, military and aerospace guidance and navigation units, and high-reliability medical imaging front ends. The parallel microprocessor interface connects directly to 8- or 16-bit data buses, simplifying integration in both legacy and new designs. From a procurement perspective, the ceramic packaging and industry-standard pin-out support long-lifecycle defense and industrial programs. Second-source availability combined with Analog Devices’ product longevity initiatives helps mitigate obsolescence risk. The monolithic architecture, with its integrated reference and clock, reduces the number of discrete precision components on the bill of materials and streamlines qualification efforts for high-reliability applications.
