DESCRIPTION:
Maxwell Technologies’ 7805ALP high-speed analog-to-digital
converter features a greater than 50 krad (Si) total dose toler-
ance, depending upon space mission. Using Mawell’s radia-
tion-hardened RAD-PAK® packaging technology, the 7805ALP
incorporates the commercial ADS7805 from Burr Brown. This
device is latchup protected by Maxwell Technologies’ LPT™
technology. The 7805ALP, 16-bit sampling CMOS A/D . The
device contains a complete 16-bit capacitor-based SAR A/D
with S/H, reference, clock, interface for microprocessor use,
and three-state output drivers. The 7805ALP is specified at a
100 kHz sampling rate, and guaranteed over the full tempera-
ture range. Laser-trimmed scaling resistors provide an indus-
try-standard ± 10V input range, while the innovative design
allows operation from a single 5V supply, with power dissipa-
tion of under 132 mW.
Maxwell Technologies' patented RAD-PAK® packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mission. In a GEO orbit, RAD-PAK® provides greater than 50
krad (Si) radiation dose tolerance. This product is available
with screening up to Maxwell Technologies self-defiened
Class K.
