® ADC0803, ADC0804 Data Sheet August 2002 FN3094.4 8-Bit, Microprocessor-Compatible, A/D Converters The ADC080X family are CMOS 8-Bit, successiveapproximation A/D converters which use a modified potentiometric ladder and are designed to operate with the 8080A control bus via three-state outputs.

These converters appear to the processor as memory locations or I/O ports, and hence no interfacing logic is required.

The differential analog voltage input has good commonmode-rejection and permits of
