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.
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.
