Abstract

PURPOSE:To simplify the constitution, by making AD conversion of a plurality of input voltages with time division through the use of one comparator. CONSTITUTION:Three analog voltage input terminals 1-3 are connected to the 1st input terminal of an analog comparator 7 via switches 4-6. A voltage divided with resistors 9-16 in series connection to a reference voltage input terminal 8 is connected to the 2nd input terminal of the comparator 7 via switches 24-30. The switches 4-6 are on- and off-controlled with a decoder 45. The output signal of the analog comparator 7 is inputted to a serial input shift register 51. That is, three analog inputs are sequentially AD-converted through time division with the switches 4-6 controlled with the decoder 45.
