• AD7710: Serial interface

    Sometimes the ADC AD7710SQ seems to start in an "unusual mode" after power up.

    The serial output bits are delayed by one serial clock cycle or the serial
    configuration input data are read or shifted one bit left (in advance).
    I use the…

  • AD7798 v AD7710 for precise measurements in presence of external vibration

    The AD7710 works well in the precense of external vibrations, but when I use
    the AD7798 the performance falls to unacceptable level in the precense of the
    same vibrations...can you explain ?

     

    The AD7710 uses a free-running filter with no chopping…

  • AD7710 input impedance different to what is explained in AN-338?

    AD7710 input impedance different to what is explained in AN-338?

    The datasheet for the AD7710 states that the input impedance is ver high.
    However, in AN338 there is a different statement, the input impedance is gain
    dependent and can be 288k for…

  • RE: Channels reading mixed from AD7710

    Hi Jellenie,

    thanks for your help. I tried what you mentioned. I'm not sure, if I did it right, but when I left connected on AD7705 only power supply, reference voltage, MCLK IN from another one with crystal, CS tied to VCC and RST provided from another…

  • Problems using AD7710

    Here's my circuit diagram. The purpose of using AD7710 is to measure the voltage of both PT100 and Rref. 

    The problem I met is that while it is possible and correct to read from and write to the control register, reading from  the data register is…

  • AD7710 读数据寄存器永远为0或0xFFFFFF

    我使用的是AD7710,控制器是STM32

    目前遇到的问题是,无论是给AD7710写控制寄存器或是读AD7710的控制寄存器,都是可以正常工作的

    但从两个通道读数据寄存器时,无论输入如何,读出的数值都为0

    我看到之前有人问过类似的问题,但ta遇到的问题与我的貌似并不太一样

    能有人给出一点思路吗?

  • AD7710的DRDY引脚

    你好,

    AD7710上电后DRDY引脚的电平值一直为低电平。在反复做读取操作时,DRDY、SDATA的电平值始终没有变化。IO口模拟时序时的电平保持时间为20us。

    请问有什么原因会导致这样的情况产生?
