ESCRIPTION
:
Maxwell Technologies’ 7872 high-speed 14-bit ADC mcrocir-
cuit features a greater than 100 krad (Si) total dose tolerance;
depending upon orbit. The 7872 consists of a track/hold ampli-
fier, successive-approximation ADC, 3V buried Zener refer-
ence and versatile interface logic. It features a self-contained,
laser- trimmed internal clock, so no external clock timng com-
ponents are required. For mnimumnoise possible, the on-
chip clock may be overridden to synchronize the device oper-
ation to the digital system The 7872 is a serial output device.
It is capable of interfacing to all modern mcroprocessors and
digital signal processors. The 7872 operates from±5V power
supplies, accepts bipolar input signals of ±3V and is able to
convert full power signals up to 41.5 kHz. It is also fully speci-
fied for dynamc performance parameters including distortion
and signal-to-noise ratio.
Maxwell Technologies' patented R

packaging technol-
ogy incorporates radiation shielding in the mcrocircuit pack-
age. It elimnates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mssion. In a GEO orbit, R

provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.
