1 6 -BIT DIGITAL-TO-RES OLVER CONVERTER

FEATURES

DESCRIPTION

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.

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.

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.

Outputs

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-
