• RE: ADUM4221 comparison to UCC21540

    Hello Patrick,

    The ADuM4221 secondary side supports higher supply voltage as compared to the UCC21540. Also, the CMTI rating of the ADuM4221 is higher than the UCC21540.

  • Can the ground B (GNDB ) of ADuM4221-1 be driven at -4V?

    Hello, 

    I wish to use ADuM4221-1  to drive C3M0015065K SiC MOSFET. This requires to be driven at a negative voltage to ensure that it stays off when required. Can the ground B (GNDB )  of ADuM4221-1 be driven at -4V? The datasheet of ADuM4221-1  says it is compatible…

  • Clock distribution to 2 DDSs (9913) and 2 ADCs (AD7769)

    Hi,

    I am goning to distribute a common 40 MHz clock to 2 DDSs and 2 ADCs. Will AD9577 work for this purpose? If not, do you have any suggestion?

    The ADC needs 5 V CLK and the DDS needs 1.8 V CLK.

    Hello Dave,

    I am facing problems with replies to your answer, so I am oppening a new dicussion with the same title.

    Please clarify your answer regarding STANAG support:

  • LTC6804-2 and LTC6811-2 reference voltage 1 and 2 at 0V.

    Hello,

    I installed 2x LTC6811-2 and then 1x LTC6804-2 on the same board and I don't have any voltage reference output at anytime. The functional diagram in the datasheets shows that VREF1 should be always present as it's generated from V+. VREF2 is not…

  • 2*2 MIMO setup

    Hello,

    Iam interested in implementing a MIMO 2*2 scenario where i will use 2 fpgas (1 as the transmitter and 1 as the receiver) where each one  will be connected with one AD-FMCOMMS3-EBZ.
    So the setup will be :
