ADC0804

⁍The ADC0804 is a commonly used ADC module, for projects were an external ADC is required. It is a 20-pin Single channel 8-bit ADC module. Meaning it can measure one ADC value from 0V to 5V and the precision when voltage reference (Vref –pin 9) is 5V is 19.53mV (Step size). That is for every increase of 19.53mV on input side there will be an increase of 1 bit at the output side.

⁍This IC is very Ideal to use with Microprocessors like  Beagle bone etc.. Or even to use as a standalone ADC module. Every ADC module requires a clock to function; this IC comes with its own internal clock so you don’t have to worry about it. Hence, if you are looking for a compact ADC module with a decent resolution of 8-bit then this IC is for you.
