• AD7401: SINC3 filtering

    We're planning to use the AD7401 with an FPGA for current measurement in a
    motor control application. The questions concern the post-processing of the
    modulator output from the AD7401. I've done some reference reading and also

  • AD7401 Bitstream

    Hello Together,

    we use the AD7401A for current measurement of our power inverter. The converters are supplied with a bootstrap circuit with the reference on the phase they are measured.An FPGA does the SIN3 Filter.

    Everything works fine!

    But now we…

  • AD7401 driver in FMCMOTCON2 project

    Received by e-mail:

    We are trying to use the FMCMOTCON2 reference design and we cannot understand why the signal "word_clock" is routed as shown in the below snapshot. I can see that the AD7401 module might need the signal for synchronization but…

  • AD7401输出数据流问题

    最近在使用AD7401芯片,有些问题不是很明白。1 ad7401是不是在MCLKIN时钟下启动采样,启动一次采样需要几个时钟?2 MDAT输出1位比特流的格式是什么,请举例说明,我ad7401配置为单极性输入。是不是对每次采样 MDAT端口输出的比特流是16位的“0” “1”组合?也就是说需要16个时钟?希望能得到详细解答,谢谢!

  • AD7401 NTSC decoding with CP Processor

    Our application requires decoding of NTSC square pixel (640x480) which is not supported by default using the SDP processor.

    I couldn’t find any example of CVBS video signal decoding thru the CP processor and it seems like in our case the video signal…

  • Common mode voltage range of the AD7401

    I have 2 questions about the datasheet of the AD7401 isolated sigma delta modulator.

    1. I could not find a specification for the common mode range of the analog inputs. The negative input of the modulator is always connected to GND.

  • (AD740*)What is the difference between AD7400 & AD7401 & AD7402 &AD7403?

    Hi !

    Our customer have interesting in AD740*.

    And they want know what is the difference between AD7400 & AD7401 & AD7402 & AD7403.

    Can you explain the difference?

    AD7401 is AD7400 external clock version.

    AD7403 is AD7402 external clock…
