DS-11802

FOUR QUADRANT MULTIPLYING SIN/COS DAC,

MICROPROCESSOR COMPATIBLE, 16-BIT HYBRID

DESCRIPTION

The DS-11802 is a small size, high

accuracy, 16-bit digital-to-sine/cosine

converter. Available in accuracies up

to 1 arc minute, the DS-11802 is con-

tained in a 28-pin DDIP and requires

+15 Vdc and -15 Vdc power supplies.

The reference input is buffered

through an op-amp to minimize load-

ing on the input signal and can accept

up to ±10 V peak. The DS-11802 is

pin programmable for gains of 0.5,

1.0, and 2.0. Two registers for the

input of the 16-bit (CMOS/TTL) natur-

al binary angle data allow for compat-

ibility with an 8-bit or 16-bit data bus.

Internally, the DS-11802 has a multi-

plying digital-to-sin/cos converter

consisting of two function generators

and a quadrant select network.

Quadrant information is available

from the two most significant bits

(MSBs). The two function generators

use the remaining angular data along

with the buffered reference voltage.

Similar to a multiplying DAC (digital-

to-analog converter), the DS-11802

uses high-accuracy resistive ladder

networks and solid-state switching to

control the attenuation of the refer-

ence voltage. The output buffer ampli-

fiers allow for up to 2 mA output drive.

FEATURES

•

28-Pin Ceramic DDIP Package

•

1 Arc Minute Accuracy

•

0.03% Radius Accuracy

•

Microprocessor Compatible -

8- and 16-Bit

APPLICATIONS

Due to the high accuracy, high reliabil-

ity, small size, low power consumption

and MIL-PRF-38534 processing avail-

able, the DS-11802 is suitable for

industrial and military ground or avion-

ic applications. Possible applications

include digital remote positioning,

resolver angle simulation, flight train-

ers, flight instrumentation, radar and

navigational systems, and PPI dis-

plays including moving target indica-

tors. Other applications are syn-

chro/resolver system development

and testing, and wraparound test of

synchro/resolver-to-digital converters.
