DSC-11524
16-BIT HYBRID D/S AND D/R CONVERTER
PIN PROGRAMMABLE FOR SYNCHRO
OR RESOLVER OUTPUT
DESCRIPTION
The DSC-11524 is a versatile multi-
plying digital-to-analog converter.
The digital input represents an
angle, and the output is pin program-
mable for either resolver, sin/cos, or
three-line synchro type output. The
reference input will accept any wave-
form, even a sawtooth for CRT drive.
Because the reference is DC cou-
pled to the output, the DSC-11524
can be used in many configurations,
such as: a digital-to-synchro/resolver
converter using a sinusoidal refer-
ence as an input; a digital-to-sin/cos
DC converter using a DC reference;
a polar-to-rectangular converter
using a reference input proportional
to the radius vector; a rotating cart-
wheel sweep generator for PPI dis-
plays using a sawtooth reference.
Packaged in a 36-pin DDIP, the
DSC-11524 is a complete D/S and
D/R converter in one hybrid module.
Hybrid technology results in low
weight, low power consumption, very
high reliability, and a wide operating
temperature range. The DSC-11524
circuit design allows for higher accu-
racy and reduces the output scale
factor variation so that the output
can drive displays directly. The out-
put line-to-line voltage can be scaled
by external resistors. Other features
include high ac and DC common
mode rejection at the reference
input, and output short circuit protec-
tion.

APPLICATIONS
Because of its high reliability, small
size and low power consumption the
hybrid DSC-11524 is ideal for the
most stringent and severe industrial
and military ground or avionics appli-
cations. All units are available with
MIL-PRF-38534 processing as a
standard option.
Among the many possible applica-
tions are computer-based systems
in which digital information is
processed, such as simulators, flight
trainers, flight instrumentation, fire
control systems, radar and naviga-
tion systems, and PPI displays
including moving target indicators.
