The AD7672 is a high‑speed 12‑bit analog‑to‑digital converter from Analog Devices. It offers selectable unipolar (0‑5 V, 0‑10 V) or bipolar (±5 V) input ranges, operates from +5 V and –12 V supplies, and dissipates only about 110 mW.
Its digital interface provides three‑state data outputs and a 90 ns bus access time, making it easy to connect to modern microprocessors. Various package options are available, including a 0.3‑inch 24‑pin DIP and 28‑pin surface‑mount versions.
