Analog to Digital Converter IC ADC0804

This ADC0804 device are CMOS 8-bit successive approximation converters ADC that use a differential potentiometric ladder – similar to the 256R products. These converters are designed to allow operation with the NSC800 and INS8080A derivative control bus with Tri-state output latches directly driving the data bus. This ADC appear like memory locations or I/O ports to the microprocessor and no interfacing logic is needed.

Besides, it have lots of features. It is an 8-bit successive approximation analogue to digital converter, ADC. The features of ADC0804 are differential analogue voltage inputs, 0-5V input voltage range, built in clock generator, reference voltage can be externally adjusted to convert smaller analogue voltage span to 8-bit resolution etc. The pin out diagram of ADC0804 is shown in the figure below.

Video below show how analog to digital converter work.
