• ad7175-8 通信失败

    大家好 我最近在用ad7175-8 这个ADC 电路焊好后我用stm32 读取芯片ID 数据手册上写ID为0x3CDx 可是为啥我读出来的结果是0x3972 各位大神帮我看看是什么问题呗 不胜感谢

    附件中是原理图  miso波形图 和mosi波形图

    我根据数据手册 向ad7175-8发信息 0x47 之后再给3个周期的sclk时钟 但是读回来的数据不对啊  

  • AD7175-8 Multiple Channel Read

    Hey,

    I am still learning how to properly communicate with this ADC with an STM32F4. I cant seem to figure out how to read the channels separately. 

    When i put voltage on AIN0 and read data from chan_1 and chan_2, the 2 channels show the same data.

  • AD7175-8 ID Register least significant 4 bits

    Hello,

    I would like to confirm the value of the AD7175-8 ID Register value. In the AD7175-8 datasheet, the 16 bit ID is listed as "0x3CDx". There is no mention to what the lowest four bits should be represented by "x". I suspect these may change based…

  • How to confirm external reference is valid on AD7175-8

    I'm planning on using an external reference with the ad7175-8 and I have a system requirement to monitor the reference to ensure the conversions are correct.  I noticed that the crosspoint mux allows for the inputs to be connected to the ±REF pins…

  • About AD7175-8 input range?

    Dear Sir:

                   I have some confuse of AD7175-8 input range as below:

    I tried to check datasheet of AD7175-8 page 3 to knew AD7175-8 input range is +(-) VREF and VREF range is 1~AVDD1, then datasheet tell us AVDD1 range is 4.5~5.5V , but ratings of input…

  • AD7175-8 driver usage

    Hello, 

    Found given example how to use AD7175-8 driver. But it looks like example describes older version of driver.

  • AD7175-8 : number of oversample

    Hello,

    I have a question about number of oversample of AD7175-8 from a customer.
    There is the comment which is the margin note of table-19 in the datasheet, is are following.

    "The settling time is rounded to the nearest microsecond. This is reflected in…

  • AD7175-8 on Raspberry Pi 3

    Dear All,

    Our project is to incorporate the AD7175-8 digital converter to Raspberry Pi 3.

    We are using the implementation file written in C that we will compile into our Linux-based environment (Raspbian):

  • AD7175-8 Using Single Ended Inputs - Only able to read Odd Numbered Channels

    Dear EngineerZone community,

    The device presenting an issue is AD7175-8 interfaced to an Atmel Sam4S via SPI communications.  It is configured to read single ended data from channels 0 through 9 at a sample rate of 59.9Hz. 

    All channels use the same Setup_Config_0…

  • AD7175-8部分模拟输入悬空导致测量不准

    目前正在开发一款基于AD7175-8的多通道高精度采集系统。

    目前遇到如下问题:

    部分模拟输入引脚悬空,这些引脚上的电压会缓慢上升,最终达到AVDD电压,此时所有模拟输入引脚都会被拉高到AVDD1,未悬空的模拟输入引脚上也会存在较大的非正常的输出电流,使得共模电压受ADC影响而提高,也因此会导致传感器输出电压产生较大误差。

    请问如何解决。
