• 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。

  • Effective noise bandwisth of AD7175-8 and AD7176-2

    Hello,

    I have a question from a customer about effective noise bandwidth of AD7175-8 and AD7176-2.

    In the datasheet for LTC2444, EFFECTIVE NOISE BW is presented in table-8.

    The customer need to know the same parameter to estimete SNR of his system…

  • AD7175-8 : XTAL1 and XTAL2 pins while using internal oscillator

    Hello,

    I have a question about XTALx pins for AD7175-8. 

    When using internal oscillator, is XTAL1 pin should connect to GND ?

    Or, can I left XTAL1 and XTAL2 pins open ?

    Best regards,

  • Can't read id register on AD7175

    I am trying to read the status register on the AD7175-2. It should read 0xCDX but I read 0x40CE as shown below. What am I doing wrong?

  • interfacing EVAL-AD7175-2 with MAX32666FTHR

    Hi.

    I don't know if this is the correct forum to ask this question. Anyway, I want to interface the EVAL-AD7175-2 with a microcontroller particularly the MAX32666FTHR. It seems I was able to understand some of the content in this wiki AD717X No-OS Software…

  • [AD7175-8] ODR not as set when using pull-up on ERROR pin

    As the title says, when using a pull-up on ERROR pin, the ODR of the AD7175-8 falls almost to half the one being set in the registers. If 62kSPS is set as ODR, ~28k is what you get if you probe the DRDY pin with a scope. 

    The datasheet states:

    The ERROR input…

  • 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…
