摘　　要：ｉｓｐＰＡＣ２０在系统可编程模拟器件集放大器、比较器、Ｄ／Ａ转换器为一体，可灵活、方便地完成放大器、有源滤波器、方波发生器等模拟电路单元的设计。还可将其与ｉｓｐ１０３２结合实现可编程的逐次逼近式Ａ／Ｄ转换器。本文给出了一个设计实例，它具有控制灵活，可方便地嵌入到电子系统设计中的优点。ispPAC20 is an analog programmable device. In it, operational amplifier, comparator, D/A convertor are contained. By using the analog programmable device, the amplifier, active filter, square wave generator can be designed. Also the analog programmable device can be conbined with isp1032 to implement a programmale successive approximation A/D convertor. The results of researching show that this kind of convertor can be embedded in electronic system conveniently. The design given by the paper is reasonable, its performance can enough satisfy the most requirements. So it is worthy of applications.
