DESCRIPTION:
Space Electronics’ 5102ALPRP is a 16-bit monolithic CMOS analog-to-
digital converter capable of 20 kHz throughput. On-chip self-calibration
achieves nonlinearity 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 calibration cycle, eliminating the
need for external trimming.
The 5102ALPRP each consist of a 2-channel input multiplexer, DAC, con-
version 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 amplifier.
The converters’ 16-bit data is output in serial form with either binary or
2’s complement coding. Three output timing modes are available for easy
interfacing to microcontrollers and shift registers. Unipolar and bipolar
input ranges and digitally selectable.
