초록 ▼

An integrated circuit includes a detector having a detecting device that detects a proximity condition and develops a parameter of electric power related thereto and a parameter measuring device coupled to the detecting device. The parameter measuring device comprises a parameter detector, and an analog-to digital converter (ADC) coupled to the parameter detector and operative in one of a plurality of operational ranges to develop a digital representation of the parameter. The parameter measuring device further includes a range selector coupled between the ADC and the parameter detector that is operative to cause the parameter detector to develop an output signal magnitude representative of the parameter of electric power wherein the output signal magnitude is within one of the operational ranges of the ADC. The detector may be used in a control for a spray device to detect motion.
