摘要：
A data conversion/output device includes a number of sensors, voltage-time conversion circuits that are arranged adjacent to respective sensors and change output levels upon the lapse of times corresponding to output voltage values from the sensors after a conversion operation start point in order to convert voltage outputs of the sensors into times. The device also includes sensed data generation circuits for outputting, as digital data, lapse times until the output levels of the voltage-time conversion circuits change after a conversion start point. The sensed data generation circuits include a counter for counting a clock signal. An operation start of the voltage-time conversion circuits and a start of count operation of the counter are staggered.
