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.

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.
