  • AD7707的采样速度问题

    我使用AD7707设计产品,晶振4.9152M,使用模拟开关8通道切换,每通道工作在50HZ,但是每各通道的增益不同,目前已经能读到数据,但是在速度方面不高,115200的时候只能4次/秒,但是按照计算115200BPS,按照每次发送8个字节指令读取,返回7个数据指令,应该可以做到10次/秒,我不是很清楚问题出在哪,我如果设置采集速度为250次/秒,也只能到5次左右,另外我没有找的AD7707哪地方有个CODE寄存器,附件是读写和设置程序,请帮我看下是什么问题,以下是设置程序:

  • AD770x经典仪表转换器常见问题解答

    AD7705和AD7706均为完整16位、低成本、Σ-Δ型ADC,适合直流和低频交流测量应用。其具有低功耗(3 V时最大值为1 mW)特性,因而可用于环路供电、电池供电或本地供电的应用中。片内可编程增益放大器提供从1至128的增益设置,无需使用外部信号调理硬件便可接受低电平和高电平模拟输入。

    AD7705拥有两个差分通道,而AD7706则拥有一个差分通道和两个伪差分通道。在定制比率应用器件时,差分基准电压输入还能提供极大的灵活性。

    AD7707是一款适合低频测量应用的完整模拟前端。这款3通道器件既可以直接从传感器接受低电平输入信号…

  • AD7790: Shift signals

    Sensor output is amplified so that signal lies between -3 and +3 V. System
    voltage is 3 V, -3V available from a voltage converter.
    Is it possible in some way to use the AD7790 as ADC in that case? What other
    possibilities are there to…
  • AD7712: Master clock

    I would like to use sigma-delta converters for a
    multi-channel (48) acquisition application. There
    is a stringent need for synchronicity between
    each converter in our application.

    I am interested in using AD7712 converters since…
