• RE: AD7492:reference

    Hi 150380jane,

       The AD7492 has a 2.5V internal reference that can be output in the REFOUT pin. The 2.5V internal reference is buffered and connected to the core 12bit SAR ADC. To stabilize the 2.5V internal reference, it is recommended to place a 100nF…

  • the noise of AD7492

    from the figure of the bellow,we use the samping frequency 100khz  to samp the signals,when the time is 40ms,the vibration sigals is coming ,but the analog sinals is no noise(by observating the oscilloscope),and the frequency of analog sinals is about…

  • AD7492 artifacts

    Hello!

    I am using the AD7492 ADC to convert an analog signal at about 0.1 MSPS but at irregular intervals I am getting single samples which are way off. The samples always contain many 1-bits near each other e.g. 0x3FF0 or oxE000. I have outputted the…

  • AD7492噪声

    下面是AD7492测试的时候,采样频率为100KHZ,我们测量的是频率10Khz的一些信号,示波器上能够看出来,模拟量是没有噪声的,但是用AD7492采样的时候,下面图上是我们约40ms的时候我们的信号,但是出现了一些毛刺,也就是噪声,怎么样能解决这些问题。

  • RE: AD7492BRUZ referencing

    Hi Regwer,

       Thanks for sharing. As I mentioned, the performance of AD7492 specification is not guarantee when placing resistor right after the REFOUT. The Evaluation board has placed a buffer on the REFOUT, this is to have enough current drive on the…

  • AD7492有没有正常模式

    我在使用AD7492芯片,这个芯片的11引脚PS/FS部分休眠和完全休眠引脚,高电平的时候是部分休眠,低电平的时候是完全休眠,我想问一下,能否不让处于休眠模式,是不是悬空的时候就可以不让处于休眠模式吗?

  • AD7492BRUZ outputting only a subset of the possible values

    I am making a sensor sampling circuit with an AVR microcontroller sampling my AD7492BRUZ ADC at about 500 Hz (low frequency just for testing).

    The problem I have is that the ADC doesn't output all digital values within its 12 bit range. Instead, it will…

  • RE: ADC used for single-pulse conversion

    Hi Postino,

    Here are some list of ADC that could be suitable for your application. You may also wanted to check the ADI website and do a parametric search and put in parameters on the ADC that you wanted to search. Please refer to the link below.
