    Hi guys,

    I'm looking at the data sheet for a ADC,
    ADC0804

    I just wanted to know what CS , WR , RD , and INTR mean... ? and how can I use them to be able to convert an incoming analog voltage at any rate.


    Thanks guys​

    CS - Chip select
    WR - Write
    RD - Read
    INTR - Interrupt

    Can you link to the datasheet?

    Why do we have both read and write ? I can understand why we have a read ( as in read in the digital value ) , but why is there a Write , and what is Interrupt... I don't think it explains it at all in the datasheet

    The ADC804 data sheet does not appear to use any of those signals. It's a serial output converter. You give it a convert command, and clock in the result of the conversion.

    Take a look at page 5 for the timing diagrams which show the order the signals need to be asserted. Page 8 also shows some example configurations. This operates much like an external memory interface.
