The CS5101A and CS5102A are 16-bit monolithic

CMOS analog-to-digital converters (ADCs) capable of

100 kSps (5101A) and 20 kSps (5102A) throughput. The

CS5102A’s low power consumption of 44mW, coupled

with a power-down mode, makes it particularly suitable

for battery-powered operation.

On-chip self-calibration circuitry achieves nonlinearity of

±0.001% of FS and guarantees 16-bit, no missing codes

over the entire specified temperature range. Superior lin-

earity also leads to 92 dB S/(N+D) with harmonics below

-100 dB. Offset and full-scale errors are minimized dur-

ing the calibration cycle, eliminating the need for external

trimming.

The CS5101A and CS5102A each consist of a 2-chan-

nel input multiplexer, DAC, conversion and calibration

microcontroller, clock generator, comparator, and serial

communications port. The inherent sampling architec-

ture 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 two’s complement coding. Three output

timing modes are available for easy interfacing to micro-

controllers and shift registers. Unipolar and bipolar input

ranges are digitally selectable
