The AD7520 and AD7521 are monolithic, high‑accuracy, low‑cost multiplying digital‑to‑analog converters. They use a thin‑film R‑2R ladder and NMOS SPDT switches to achieve 10‑bit (AD7520) or 12‑bit (AD7521) resolution with TTL/CMOS compatible operation.
The document lists detailed electrical specifications, absolute maximum ratings, pin descriptions, package dimensions, and example application circuits for unipolar and bipolar operation. It also includes test circuit diagrams, die characteristics, and ordering information for the PDIP packages.
