• AD7476, sample and hold functionalities

    Hi,

    I am planning to use AD7476 in my application.

    I want to know the timing diagram of the sample and hold circuit used for this application.

    ADC takes the value when it is sampled and holds for certain amount, can i know the timing diagram for the same…

  • ad7476的SDATA

    时序,电压都对。但是sdata引脚输出的电压只有0.0几。我的是不是芯片坏了

  • AD7476 missing codes

    I cannot get a the AD7476 in my circuit to produce and output code greater that 4080 Decimal.  All codes below this value are produced and within spec (see the INL graph below).  I do see the effects of large code transitions from a string of eight "1"s…

  • Multiple AD7476 (PmodAD1)

    Hi there,

    Following on from the successful build and test of a single PmodAD1 : http://ez.analog.com/message/123360

    I have modified the reference design to have two AD7476A HDL blocks and also included other necessary changes to route through a dma…

  • AD7476没有数据

    我给了16个时钟上电,然后循环读取数据。

    我用的是stm32,并且时钟频率是50MHz,也就是说一个时钟周期20ns。

    然而AD7476,依旧读不了数据,时序应该是满足的。

  • AD7476读不出数据

    我用的是SPI通信,CS与SCLK都在读取时拉低了,但是SDATA一直没有数据,用的是CN0303接adxl001。CN0303的J4端口外接处理器的SPI。我测量电压时发下,CN0303上的CS自带电压,3.3V,请问我的AD7476坏了?还是由于什么原因导致没有数据。(CN0303已接5V电源,ADXL001与CN0303已确保连接正确,程序仿真一步一步读取不行,直接运行也读取不了)。

  • AD7476 Interfacing Code in Verilog

    Hi,

        I am trying to use a PMOD AD1 from digilent, which has 2 AD7476s. I am using it with a Zedboard and need some kind of basic reference code for interfacing the ADC. I have posted my code below. I can see it converting the data, on the DataA pin digital…

  • 关于AD7476和AD7476A的不同点

    最近对AD7476和AD7476A进行了关注,想问一下这两款芯片最大的不同点在哪里。

    我对这两款芯片的看法是

    AD7476A提供了KS-6这样更小的封装,以及71 dB SNR at 100 kHz的表现。但是我还是希望得到专家的解答,即这两款芯片有何差别?非常感谢!

  • AD7476 behaves like reference is only VDD/2.

    Hello, I am trying to understand a board, that contains an AD7476ARTZ. My question is certainly very low level, I am a physicist not an engineer, so I hope you don't mind my ignorance.

    The problem is, that the digital output seems to be about twice…
