GENERAL DESCRIPTION
The AD7859/AD7859L are high speed, low power, 8-channel, 12-bit ADCs which operate from a single 3 V or 5 V power supply, the AD7859 being optimized for speed and the AD7859L for low power. The ADC contains self-calibration and system calibration options to ensure accurate operation over time and temperature and have a number of power-down options for low power applications.
