RadHard Resolver-to-Digital Converter

A RadHard RDC Solution!

Cobham offers RadHard Resolver-to-Digital Converters (RDC). An RDC is an integrated circuit (IC) used in shaft angle control systems to convert a resolver's SINE and COSINE analog signals to an angle represented by digital output configurable for 10, 12, 14 or 16 bits.

Celebrating 10-years of Flight! Cobham's RadHard Resolver-to-Digital Converters (RDC) is in demand for long term missions. 1Mrad and SEL immune to 100 MeV-cm2/mg, the RDC has 10 years of proven flight history.

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

Note: Cobham's Radiation Hardness Assurance Plan is DLA Certified to MIL-PRF-38534, Appendix G.
