GENERAL DESCRIPTION
The AD7851 is a high speed, 14-bit ADC that operates from a single 5 V power supply. The ADC powers-up with a set of default conditions at which time it can be operated as a read-only ADC. The ADC contains self-calibration and system calibration options to ensure accurate operation over time and temperature and has a number of power-down options for low power applications.
