摘　　要：基于AD603设计了一种程控放大滤波器,系统主要由AD603模块、MAX262模块、STM32主控模块、键盘及显示模块等组成。经测试,滤波器通频带宽为100Hz～50KHz,在O～50dB增益范围内实现了5dB步进可调,系统可设置为低通滤波或高通滤波两种状态,截止频率在1K～25KHZ范围内实现了1K步进可调。Thiskind of programmable amplifier whose system mainly contains by AD603 module,MAX262 modu le,STM32 master module,keyboard and LED display module is designed based on AD603.This system could be designed as two states,low pass filter and high pass filter.The filter can achieve 5dB stepper ad justable within 0~60dB gain range,pass band width of 100Hz^50KHz,cut off frequency within 1K^25K with 1 K stepper adjustable.
