The AD673 is a complete 8-bit successive approximation analog-to-digital converter consisting of a DAC, voltage reference, clock, comparator, successive approximation register (SAR), and 3-state output buffers—all fabricated on a single chip. No external components are required to perform a full accuracy 8-bit conversion in 20 µs. The AD673 incorporates advanced integrated circuit design and processing technologies. It can handle unipolar and bipolar inputs and operates on +5V and -12V to -15V supplies. Additionally, the AD673 is compliant with MIL-STD-883 standards.
The AD673 is a complete 8‑bit successive‑approximation analog‑to‑digital converter that integrates a DAC, voltage reference, clock, comparator, SAR and 3‑state output buffers. It is offered in 20‑pin ceramic and plastic DIP packages and in two temperature‑grade versions (J and S).
The datasheet provides functional block diagrams, pin‑out tables, electrical specifications, timing diagrams, grounding recommendations, and interfacing guidelines for microprocessor and sample‑hold applications, enabling designers to implement the converter in unipolar (0‑10 V) or bipolar (‑5 V to +5 V) modes.
