ABSTRACT:
An analog/digital converter in the present invention compares sequentially with respect to the elapse of time an inputted analog signal with multiple-bit signals corresponding to reference voltages of multiple levels so as to output a digital signal. The analog/digital converter includes a shift register for tracking the termination of the comparisons of each bit signal at every bit with the elapse of time, a selector for sequentially storing in an internal register select shift register bits representing comparison termination signals, and a central processing unit for selecting one of the termination signals stored in the internal register so as to output it to the flag register. The termination signal may be output to the flag register before digital conversion is complete thereby enabling the CPU to prepare to read the final result while digital conversion is still being performed.
