Description
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
