摘　　要：MAXIM公司生产MAX２６０可编程滤波器具有数字可编程控制功能，它具有独立的１２８级Ｑ值控制和６４级中心频率可编程控制，可靠性高，对使用环境要求低。文章介绍利用８０Ｃ５５２单片机控制可编程滤波器ＭＡＸ２６０，从而实现多功能智能滤波器。它由键盘控制液晶ＬＣＤ显示被设置的工作状态，给仪器的设计带来极大的方便，适合各类石油仪器的数据采集和信号处理电路中的滤波器。This paper introduces the interior structure and powerful function of MAX260 universal active filter made by MAXIM Corpolation. It is of independent control functions of 128 - step Q and 64 - step center frequency. Using a 80C552 single chip microcomputer and MAX260 can form an intelligent and universal active filter. Its function is controlled by keyboard and its status is displayed on LCD.It offers great convenience for design of instrument and it can be as a special filter in data acquisition and signal processing circuit of petroleum instrument.
