7. CONCLUSION

The CS556x/7x/8x family of devices offers an exceptional alternative to SAR devices in multiplexed applications.

Due to their digital filter with single-conversion settling, the input to the ADC can change from one end of full scale

to the other between conversions and still maintain full accuracy. Since delta-sigma converters have far superior

differential non-linearity (DNL) specifications and excellent noise performance, they provide a performance upgrade

path from conventional SAR ADCs. They also offer 24-bit resolution which is unattainable with SAR devices today.
