The AD2S80A is a variable resolution, monolithic resolver-to-digital converter contained in a 40-pin DIP or 44-pin LCC ceramic package. It is manufactured on a BiMOS II process that combines the advantages of CMOS logic and bipolar high accuracy linear circuits on the same chip. The converter allows users to select their own resolution and dy- namic performance with external components. This allows the users great flexibility in defining the converter that best suit their application.
The AD2S80A resolver‑to‑digital converter is offered in 40‑pin DIP and 44‑pin LCC packages. It uses a BiMOS II process and provides ratiometric tracking conversion with selectable resolution (10, 12, 14, or 16 bits) and user‑defined dynamic performance via external components. The device includes a velocity analog output and operates over a 50 Hz‑20 kHz reference frequency range.
Typical applications include brushless and AC motor control, process control, CNC machine tools, robotics, and military servo systems. The converter is available in commercial and military temperature‑range versions and meets MIL‑STD‑883B Class B requirements.
