The ADC0803 family is a series of three CMOS 8-bit successive approximaTIon A/D converters using a resisTIve ladder and capaciTIve array together with an auto-zero comparator. These converters are designed to operate with microprocessor-controlled buses using a minimum of external circuitry. The 3-State output data lines can be connected directly to the data bus.
