    Dumb Resistor Question

    user_408334244

      Hi All

         

      Dumb question of the day!  was just looking at the Cypress tutorial on Digital Filtering. Can anyone please tell me why the resistro connecting the Opamp Follower to the ADC is 100K? The opamp datasheet states that it can handle 10mA and if running at 2.5V, this results in 25uA. Is there something that I have missed or am I just being extra dumb today?
