General Description
CS5101A General Description
The CS5101A and CS5102A are 16-bit monolithic CMOS analog-to-digital converters capable of 100 kHz (5101A) and 20 kHz (5102A) throughput. The CS5102A's low power consumption of 44 mW, 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 linearity also leads to 92 dB S/(N+D) with harmonics below -100 dB. Offset and full-scale errors are minimized during the calibration cycle, eliminating the need for external trimming.
The CS5101A and CS5102A each consist of a 2-channel input multiplexer, 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 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 are digitally selectable.
