DRC-11522
TWO-CHANNEL DIGITAL-TO-RESOLVER
CONVERTER
DESCRIPTION
The DRC-11522 is a dual 16-bit digital-
to-resolver (D/R) converter. Each chan-
nel is independent from the other with
the exception of the 16 digital lines.
The DRC-11522 allows the user to pro-
gram the gain of the resolver output.
Packaged in a 36-pin double DIP, the
DRC-11522 is two digital-to-resolver
converters in one hybrid module.
Using an AC reference input, the DRC-
11522 is a digital-to-resolver convert-
er. When using a DC reference input,
the unit can be used as a hybrid digital-
to-sin/cos DC converter. With the refer-
ence input proportional to the radius
vector, the DRC-11522 converts polar
to rectangular coordinates.
The circuit design in the DRC-11522
allows for higher accuracy and
reduces the output scale factor varia-
tion so that the output can drive dis-

voltage can be scaled by pin program-
ming. Other features include buffered
reference input, and a wide operating
temperature range.

APPLICATIONS
Because of its high reliability, small
size and low power consumption, the
DRC-11522 is ideal for the most strin-
gent and severe industrial and military
ground or avionics applications. All
units are available with MIL-PRF-
38534 processing.
Among the many possible applications
are computer-based systems in which
digital information is processed, such
as simulators, flight trainers, flight
instrumentation, fire control systems,
radar and navigation systems.
