DR-11800

16-BIT DIGITAL-TO-RESOLVER CONVERTER

DESCRIPTION

The DR-11800 is a small size, high

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

converter. Available in accuracies up

to 1 arc minute, the DR-11800 is con-

tained in a 28-pin, one-square-inch

hermetically sealed package and

requires +15 Vdc and -15 Vdc power

supplies. The reference conditioner

allows for either 115 Vrms or 26 Vrms

reference input for a 6.8 Vrms sin/cos

output. Two registers for the input of

the 16-bit (CMOS/TTL) natural binary

angle data allow for compatibility with

an 8-bit or 16-bit data bus.

Internally, the DR-11800 has a multi-

plying digital-to-sin/cos converter

made of two function generators and

a quadrant select network. Quadrant

information is available from the two

most significant bits. 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 DR-

11800 uses high accuracy resistive

ladder networks and solid state

switching to control the attenuation of

the reference voltage. The output

buffer amplifiers allow for up to 2 mA

output drive.

FEATURES

•

28-Pin Square Package

•

1 Arc Minute Accuracy

•

0.03% Radius Accuracy

•

Microprocessor Compatible -

8- and 16-Bit

APPLICATIONS

High accuracy, high reliability, small

size, low power consumption and

MIL-PRF-38534 processing avail-

ability, make the DR-11800 suitable

for industrial and military ground or

avionics applications. Possible appli-

cations include digital remote posi-

tioning, resolver angle simulators,

flight trainer, flight instrumentation,

radar and navigational systems, and

PPI displays including moving target

indicators. Other applications are syn-

chro/resolver system development

and test, and wraparound test of syn-

chro/resolver-to-digital converters.
