The is an ultra-tiny 16-bit Analog-to-digital Converter ADC accepts a single-ended analog input voltage and communicates through an SPI interface. It uses a delta-sigma modulator as a converter core and provides single-cycle settling time for multiplexed applications. The internal oscillator does not require any external components. The ADC includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude. It is capable of up to 30 conversions per second and due to the very large oversampling ratio, has extremely relaxed anti-aliasing requirements. The ADC includes continuous internal offset and full-scale calibration algorithms which are transparent to the user, ensuring accuracy over time and over the operating temperature range. The converter uses its power supply voltage as the reference voltage and the single-ended, rail-to-rail input voltage range extends from GND to VCC.
