Analog Devices circuits from the lab reference circuits are engineered and tested for quick system integration to help solve design challenges ranging from common to complex. Reference circuits are smaller, modular designs that are more broadly applicable than application-specific reference designs.

Each reference circuit is documented with test data, theory of operation, and component selection decision criteria. In addition, reference circuits are tailored to meet real-world system integration needs and may also include board layout schematics, CAD tools models, device drivers, and evaluation hardware.
