ADC0804 is a very commonly used 8-bit analog-to-digital converter. It works with 0V to 5V analog input voltage. It has a single analog input and 8-digital outputs. Conversion time is another major factor in judging an ADC, in ADC0804 conversion time varies depending on the clocking signals applied to CLK R and CLK IN pins, but it cannot be faster than 110 μs.
We already know that analogue-to-digital (ADCs) converters are the most widely used devices for information securing to translate the analog signals to digital numbers so microcontrollers can read them easily. There are many ADC converters like ADC0801, ADC0802, ADC0803, ADC0804 and ADC080.
