• 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.

    About ADUM4221/ADUM4121 magnetic isolation and VDD1 power supply

    1.ADUM4221/ADUM4121 is magnetic isolation. In PCB design, it is usually close to the main transformer. Will the transformer and the internal isolation coil of ADUM4221 interfere with each…

  • [hurry]LTC6811-1 & LTC6811-1's VREG is not work.


    (Please refer to the circuit diagram)

    BMS was configured using LTC6811-1. 20cells were connected using two ICs.(LTC6811-1 & LTC6811-1)

    When the BMS board is power-on, no SPI-data communication.

    I checked, the resistance level was low like a short…

  • AD9523-1  Can I precisely adjust output clock frequency with AD9523-1 (EVAL-AD9523-1)?


    I would like to inquire if it is possible to achieve precise frequency control with EVALZ - AD9531-1? I'm interested in generating a clock signal that is a multiple of femtosecond laser output pulse rate, which can be something close to 80…

  • HMC666_using IF pin without 1:1 transformer

    Hello Team.

    1:1 transformer applied in IF pin is expensive.

    so we want to use without transformer.

    is it possible that?

    Can you support solutions?

  • RE: ADP5091-1-EVALZ board

    Hi John,

    There may be a little confusion. You can see the equation of SETBK, SETSD and SETPG are same but TERM equation is different. So you can select the resistor from column 2 and 3 when you calculate the SETSD, SEBK or SETPG. Only for TERM, you need…
