摘要：
A multiple input AD conversion apparatus includes a first unit AD converter including a plurality of first conversion stages connected in cascade to convert a first analog input signal to a first digital output signal, a second unit AD converter including a plurality of second conversion stages connected in cascade to convert a second analog input signal to a second digital output signal, and an operational amplifier shared between the first conversion stage and the second conversion stage in a time sharing.
