ADC0803/0804
CMOS 8-bit A/D converters

DESCRIPTION
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.
The differential analog voltage input allows for increased
common-mode rejection and provides a means to adjust the
zero-scale offset. Additionally, the voltage reference input provides a
means of encoding small analog voltages to the full 8 bits of
resolution.
