ABSTRACT:
In a semiconductor integrated circuit device having an A/D converter incorporated therein, a plurality of input channels are provided and input analog signals supplied therefrom are respectively held by a plurality of sample-to-hold circuits. The analog signals are simultaneously sampled by using such a pipeline operation that a first sampling is performed so that an analog signal held by the first sampling is A/D-converted and a second sampling is performed so that an analog signal held by the second sampling is A/D-converted, and the plurality of sample-to-hold circuits.
