摘　　要：在常用模拟量采集电路的基础上,提出了一种采集范围和采集模式可配置的模拟量采集电路,在接口复用的情况下,可同时满足用户对差分电压和单端电压、小电压采集及大电压采集的需求,从而大大降低模拟量采集电路的空间占用,提高了产品的通用性。In this paper,on the basis of traditional analog acquisition circuit,a type of analog acquisition circuit with configurable range and mode is proposed,which can meet the needs of users for differential voltage and single-ended voltage,small voltage acquisition and large voltage acquisition at the same time in the case of interface multiplexing.This idea can reduce the space occupation of analog acquisition circuit and improve the versatility of the product effectively.
