    Trying to establish communication between ADC and  controller via SPI. 

    I want to read the conversion result. The default SPI library is not available in the Tiva peripheral library, therefore…

  • AD7177-2, Missing conversions

    Hi,

    I'm having a particularly weird issue where I'm not receiving half of the converted values. When streaming conversions, I will receive three (seemingly) consecutive conversions, and then three or four conversions disappear, and then I'll get…

  • CRC polynomial in AD7177-2

    Hello! 

    I have some difficulties with CRC in AD7177. 
    In datashit (AD7177-2 datasheet page 42) it is said that an 8-bit polynomial is used.
    But then, in the description, I see the polynomial x^8+x^2+x+1 with the highest power - 8.
    Accordingly, the polynomial…
  • Spurious frequency in AD7177-2

    Hi,

    I'm using the high performance AD7177-2 adc in the evaluation board EVAL-AD7177-2SDZ because we need to achieve the highest possible resolution (in terms of dynamic range). I'm evaluating the rms noise when the inputs are shortcut (or shorted…

  • Questions about AD7177-2 sample rate

    My project need measure 12 channels signal,I use 3 AD7177-2,and 4 channels for each AD7177-2. These 3 AD7177-2 share a same 16Mhz clock,share a SPI BUS, and CS signals connect different GPIOs. I configure AD7177-2 to 200Hz sample rate, thus 50Hz for each ch…

  • RE: Inconsistent register values from AD7177-2

    Hi,

    I think we can use a single thread for this. https://ez.analog.com/data_converters/precision_adcs/f/q-a/119182/reading-only-16-bit-values-from-ad7177-2 

    Let me check on this and I'll let you know if I have think of any other suggestions to solve…

  • RE: ad7177-2  32位ADC转换

    你好!问你关于校准的问题:

    34401A测试电压为1.26098V    Ad7177-2测试电压为1.25996V    这个AD7177-2怎么校准呢?

  • AD7177-2, unstable channel registers

    Hi,

    Does the chip sometimes alter channels without user intervention? I've written SPI code that will set the ADC mode and CH0 to certain values. When I read from the ID and ADC mode registers, everything is fine ... but when I read from the CH0 register…
