摘　　要：介绍一种双探头压力计,它使用了AD7705,该器件可以把微小低频模拟信号直接转换成数字信号,从而可以简化电路设计,减少部分芯片。A dual-sensor pressure gauge is introduced, in which the processor AD7705 is utilized. AD7705 can convert the weak input signals coming directly from a sensor to a serial digital output, significantly simplifying the design of circuit. The functional characteristics and working procedure of AD7705 are described. The time sequence and the interface with 89C2051 are also given in this paper.
