Product Highlights

The RD19230EX-300 evaluation board is used to evaluate DDC's RD19230FX 16 bit monolithic tracking resolver to digital converter. The RD19230FX is a ... [more]

DDC is the world's leading supplier of Synchro/Resolver-to-Digital (S/R-D), and Digital-to-Synchro/Resolver (D-S/R) components - the smallest, most accurate converters available, and the building blocks for DDC's card level products. Most of these chip and hybrid converters are based on custom monolithic designs, yielding the most reliable converters ever offered.

Notes:

Package Type designation refers to the number of pins along with style of package. P – plug-in, F – flat pack, DDIP – double dip, TDIP – triple dip, QFP – quad flat pack, TQFP – thin quad flat pack, J – J lead, PGA – Pin Grid Array.
Monolithic Resolver to Digital converters can be configured for synchro mode with external components.
In the Function column: A slash ‘/’ indicates a conversion to (i.e. R/D is resolver to digital) and a dash‘-’ indicates the part has both capabilities.
Standard product also available in equivalent size flat pack.
Optional packaging available for many products, consult factory
