ispPAC20 is an analog programmable device. In it, operation amplifier, comparator and 8bits D/A converter are contained. By using the analog programmable device, amplifier, active filter and square wave generator can be designed. Also the analog programmable device is combined with isp1032E70-LJ84 to implement the countable A/D converter. The results of implementing show the programmable and countable A/D converter can be embedded in electronic system. The countable A/D converter is a typical application of analog programmable device and programmable logic device. The design given by the paper is reasonable, the performance of the countable A/D converter can satisfy the requirement. It is worthy of application.
