• AD7656 Analog Digital Converter

    Hi everyone,

    I'm trying to use AD7656 for Analog conversion, controlled by a microcontroller. I have used the circuit recommended on page 22 of the datasheet for a parallel conversion with external reference, but it doesn't work. I checked the different…

  • Connection pins on AD7656

    Hi there. Having a bit of a problem here. I have on my board  +5V, -5V and 3.3V and GND Lines. I am working with the AD7656 (Analogue to digital converter. My logical power input Vdrive is connected to the 3.3V and all other power inputs are using +/-…

  • RE: AD7606 and AD7656 Evaluation Boards Schematic and PCB

    Hi John,

    You can check the schematic and the documentation for the AD7656 and AD7606 at the ADI website and search for the part. If you purchased the evaluation board, there should be a CD in the package included, that cotains the software and documentation…

  • AD7606 analog range appears to be only -0.5 to +0.5V?!?


    Having a strange issue with the AD7606 analog chip.  In older designs we have used the AD7657 without any issue so was suprizing that having a fit with the AD7606.

    There is a delay between the +5V and +3.3V on power up

    All signals on the digital side…

  • RE: Data input from EVAL-AD7656-1SDZ does not provide valid data

    Hi, Marek.

    Apologies for the delayed response.

    I have looked at your link connections and everything seems to be in order except for link 28 which should be on C instead of A for data destination to be the external socket. I also see that RESET (LK8…

  • RE: Measurement of pulse amplitude - suggestion for ADC

    Hi Henning,

         We have some I2C ADC interface that may fit your application, you may check the AD799x. Just like to ask on when are going to use the trigger feature, is it when the pulse amplitude hit some kind of limit or outside the range? I am also…

  • 把握黄金急救时间,ADI自动体外除颤器(AED)解决方案免费下载ing!

    你知道心源性猝死(SCD)吗?

    心源性猝死是指急性症状发作后1小时内发生的以意识突然丧失为特征的由心脏原因引起的自然死亡,而且心源性猝死90%以上发生在医院外,但是这类猝死病人的黄金急救时间只有5-10分钟,超过10分钟的抢救存活率不到1%。

    当发生心源性猝死(SCD)时,唯一的救治手段是胸外按压+心脏除颤,及时除颤是迄今公认制止心脏猝死的最有效方法。

    对此,ADI推出了自动体外除颤器(AED)解决方案,可以自动诊断可能危及患者生命的心室纤维性颤动和心室性心博过速两种心律失常症状。
