The analog signal (AIN) is acquired on the falling edge of the clock input (CLK). The acquired analog signal is
converted to a digital code and is output from the digital outputs (D8 to D1, OF) on the clock falling edge delayed three
clock cycles from the clock cycle in which the analog signal was acquired.
