CMOS 8-bit A/D converters  
ADC0803/4-1  
DESCRIPTION  
PIN CONFIGURATION  
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.
