• ADuC706x: weak internal pull-up strong enough for ADuM241E's input?

    When measuring the voltage on pins of an ADuC7061 that are configured as digital inputs with internal pull-up enabled (the default for many pins after Reset), I'm observing values between 1.8 to 2V, depending on the DMM/oscilloscope used, while DVDD is…

  • Quiescent supply current for ADuM24xE

    Hello,

    I have two questions about quiescent supply current for ADuM240E/ADuM241E.

    Q1. Are the test conditions correct ?

        The quiescent supply currents are indicated in table1 and table3 which are printed in datasheet. Idd1 and Idd2 have two current…

  • RE: ADAS3022转换结果回读

    可能的原因是ADum241E存在延迟,在芯片的通信过程中,由于速率过快, 使得延迟大于了时钟周期,影响时序

  • RE: ADUM4154 with 2.5V Vdd

    Hi, cdubs,

    -0.5 to 7V is from the absolute max ratings (Table15 in the ADuM4154 datasheet). Table 14 has the recommended operating conditions, which are 3.0V to 5.5V.  The ADuM4154 cannot be supplied with 2.5V. 

    If the design requires a 2.5V supply, the ADuM141E…

  • RE: Layout - unused pins

    Ah, okay, I see.  It turns out that digging through the digital isolators more thoroughly, I found a better one.  The ADuM241 works as low as 1.8V, is 4-channel and can do 150 Mbps, so it's perfect.

    Regarding the different ground pins on the ADuCM350…
