摘要
简要介绍美国AD公司采用Σ-Δ技术生产的性能优越、24位分辨率的模数转换集成电路AD7710,它具有分辨率高、线性度好、低功耗、高性价比等优点。着重介绍了AD7710与单片机89C51的接口。AD7710特别适合测量倾角传感器输出的低频小信号,在采用软硬件的抗干扰措施后,使倾角传感器达到了预期的精度。
It briefly introduces high performance and 24-bit resolution analog to digital converter AD7710 adopted Σ-Δ technology and produced by AD Company of the U.S.A., with high resolution, linearity ,ratio of performance to price and low consumption, etc.It emphasizes the interface of AD7710 and 89C51. AD7710 is especially fit for measuring the weak and low frequency signal. Angle sensor achieves expected precision after introducing anti-interference measures of software and hardware.
