First Monolithic Resolver-to-Digital Converter

2S81 Resolver-to-Computer Interface Chip Provides 12-Bit Outputs; Accurate, Simple, Inexpensive, It Operates at Speeds up to 260 rev/sec, Has Velocity Output

The 2S81 Resolver-to-Digital Converter converts the output sine and cosine signals from ac position-measuring devices such as resolvers, to a digital word representing the angle being measured. The 2S81 is a low-cost, compact solution to the difficulties—both technical and cost—of interfacing resolver transducers to digital systems. Read full article
