• AD7608 REGCAP pin 36 and Pin39

    Hi, 

    Please see the attached circuit. We have a pcb using ad7608, the product has been in production. 

    It seems working ok, but now I found that there is an error in the circuit: Pin36 and Pin39 were short together.

    The datasheet said that "These output…

  • AD7608 内置REF 电压异常

    产品使用了AD7608整个芯片,SCH采用的是手册中推荐的方式,现在测试发现会有很小概率出现REF异常。

    出现异常的时候,测量REFCAPA,REFCAPB电压为4.078V,REFOUT电压为2.276V,REGCAP1电压为2.446V,REGCAP2电压为2.363V

    产品配置的是使用内置REF,REFSELECT引脚是直接接在3.3V上面。

    请问出现这样异常情况是本身器件问题还是其他的什么原因。

    谢谢 

  • AD7608 + SPI problem

    The datasheet of the AD7608 mentions the AD7608 being SPI compatible.
    I found the SCLK and SS but i havent found the pins for MISO and MOSI.

     

    The MISO pin should connect to the DOUT A/DOUT B pin of the AD7608. The DOUT A
    pin is pin 24 and DOUT…

  • What type is AD7608's BUSY output signal? is it open-source or open-collect?

    Hello,

    I want to use mulitple AD7608 chips.

    Can I monitor one singal that each BUSY signal is tied together(wire-or connect)?

    Thanks in advance.

  • AD7608 supply

    I am using the AD7608. The datasheet only specifies a total current of 27mA @ 5V for Vanalog & Vdrive.

    Like already discussed in a former topic (https://ez.analog.com/data_converters/precision_adcs/f/q-a/25649/ad7608-supply-currents/381411#381411
