RadHard Resolver-to-Digital Converter

A RadHard RDC Solution!

Aeroflex Plainview offers RadHard Resolver-to-Digital Converters (RDC). An RDC is an integrated circuit (IC) used in shaft angle control systems to convert a resolvers' SINE and COSINE analog signals to an angle represented by a 10 to 16 bit digital value.

The new enhanced RDC5028C is available now and recommended for all new designs.

Note: Aeroflex Plainview’s Radiation Hardness Assurance Plan is DLA Certified to MIL-PRF-38534, Appendix G.
