• AD7457: Discontinuous clock

    We need to connect the AD7457 to the SPI bus of the MPC8347E. The idea was to
    use a general purpose IO to control the CS\ of the AD7457, then read out the
    result of the conversion.

    We have 2 questions about this.

    1: can the AD7457…
  • AD7457: Filter requirements

    1) Is it necessary to use some antialiasing filter in the input of ADc for DC
    measuring only? (12bit, about 10 ksps, only DC signal)
    2) Is it suitable to use 0.1uF ceramic capacitor in parallel with 10uF CERAMIC
    capacitor (both SMD, 0805…
  • AD7457的驱动问题

    ad7457 采集模拟量,一般如果1V稳定输入,它会跳多少?

    现在用ad7457采集,1V稳定的,万用表测,不跳,稳定在1mv以下。AD7457测量跳动±2mv,不知道正不正常。

    前面应该是4个零,然后跟数据。现在读出的数据,4个前导位不是零,是0001,不知道为什么。测量数据比实际的大一倍,如果去掉最高4位,数据又不对了。在下降沿读的数据。在CS为低时,SCLK用输出吗?

  • Strange bump in spectrum

    Hello,

    We sample an Analog signal using AD7367 and then reconstruct it using AD5554. It is done almost simultaneously for 2 or 4 channels and we checked and there is no cross-talking between the channels.

    We test 1 channel at teh time and the same problems…
