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.
