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 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-
