DR-11525
16-BIT HIGH FREQUENCY HYBRID
DIGITAL-TO-RESOLVER D/R CONVERTER
DESCRIPTION
The DR-11525 is a versatile multiply-
ing digital-to-resolver converter. The
digital input represents an angle, and
the output is resolver type, sin/cos.
The reference input will accept any
waveform, even a sawtooth for CRT
drive. Because the reference is dc-
coupled to the output, the DR-11525
can be used as: a digital-to-resolver
converter using a sinusoidal refer-
ence as an input; a digital-to-sin/cos
dc converter using a dc reference; or
a polar-to-rectangular converter using
a reference input proportional to the
radius vector; or a rotating cartwheel
sweep generator for PPI displays
using a sawtooth reference.
Packaged in a 36-pin DDIP, the DR-
11525 is a complete D/R conver ter in
one hybrid module. Hybrid technology
results in low weight, low power con-
sumption, very high reliability, and a
wide operating temperature range. The
DR-11525 circuit design allows f or high-
er accuracy and reduces the output
scale factor variation so that the output
can drive displays directly. The output
line-to-ground voltage can be scaled by
external resistors. The DR-11525 also
includes high ac and dc common mode
rejection at the reference input
APPLICATIONS
Because of its high reliability, small size
and low power consumption, the hybrid
DR-11525 is ideal f or the most stringent
and severe industrial and military
ground or a vionics applications.All units
are available with MIL-PRF-38534 pro-
cessing as a standard option.
Among the many possible applica-
tions are computer-based systems in
which digital angle information is
processed, such as synchro/resolver
simulators, flight trainers, flight instru-
mentation, fire control systems, IR,
radar and na vigation systems.In addi-
tion, the DR-11525 is ideal for motor
and robotic control test systems.
