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