DESCRIPTION:
Maxwell Technologies’ 5102ALPRP is a 16-bit mono-
lithic CMOS analog-to-digital converter capable of 20
kHz throughput. On-chip self-calibration achieves nonlin-
earity of ±0.001% of FS and guarantees 16-bit no miss-
ing codes over the entire specified temperature range.
Offset and full-scale errors are minimized during the cali-
bration cycle, eliminating the need for external trimming.
The 5102ALP each consist of a 2-channel input multi-
plexer, DAC, conversion and calibration microcontroller,
clock generator, comparator, and serial communications
port. The inherent sampling architecture of the device
eliminates the need for an external track and hold ampli-
fier.
Maxwell Technologies' patented RAD-PAK® packaging
technology incorporates radiation shielding in the micro-
circuit package. It eliminates the need for box shielding
while improving the TID performance in most space
environments. This product is available with screening
up to Maxwell Technologies self-defined Class K.
