Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Introduction to ADC0804. In electronic engineering different modules used to conversion of analog signal into a digital signal. These tools are recognised as analog to digital converter or ADC. Thes signal converter also used to find the value of input current and voltage. Normally the output of these converters are 2 binary numbers but other values are also possible. These analog to digital converter are available in different structure scheme but mostly they are available in integrated circuits packaging.
The working ability of these signal converter depends on their bandwidth and signal to noise ration (SNR). Their bandwidth can be fined by their sample r ...
