Abstract：In order to achieve required eighth-order bandpass analog filter design fast and accurately ,to ensure the per-formance of filtering and gain of underwater acoustic signal receiver system ,a design that implementing eighth-order band-pass analog filter quickly is proposed in this paper which is based on the MAX274 chip of Maxim .Combined with the index of underwater acoustic signal receiver system ,the filter design software parameters are setted ,bandpass filter frequency re-sponse curve is obtained and verified by Multisim simulation ,it’s observed that the bandpass filter’s filtering and gain per-formance in the corresponding frequency band is fine .The advantages of small size ,monolithic integration and convenient de-bugging ,make the MAX274 chip more suitable for the filter design of the system .
