ESCRIPTION
:
Maxwell Technologies 5675 is a 14-bit resolution high-
speed digital to analog converter. The 5675 is designed
for high-speed digital data transmission in wired and
wireless communication systems. The 5675 has exce-
lent spurios free dynamic range (SFDR) at high interme-
diate frequencies.
The 5675 operates from a single-supply voltage of 3.3V.
Power dissipation is 820 mW at fclk = 400 MSPS, fout =
70MHz. The 5675 provides a nominal full-scale differen-
tial current output of 20mA, supporting both single-
ended and differential applications. Theoutput can be
directly fed to the load with no additional external output
buffered required.
Maxwell Technologies' patented R

AK
® packaging
technology incorporates radiation shielding in the micro-
circuit package. It eliminates the need for box shielding
while providing the required radiation shielding for a life-
time in orbit or space mission. In a GEO orbit, R
AD

AK
®
provides greater than 100 krad(Si) radiation dose toler-
ance. This product is available with screening up to
Class S.

1. Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recom-
mended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect
device reliability.
