  • RE: ADA4930-1 with AD9235

    Hi Gauzz, bandwidth - 6MHz. I choose between ADA4932-1 and ADA4930-1. Just ADA4930-1 is simple in choice of level Vocm, because I can use Vref = 1 V from AD9235. But in this case ADA4930-1 is used with Gain < 1, is it good?

  • ADA4930-1 in the power-down mode

    Hello,

    What is the output impedance (or model) of ADA4930-1 when switched off using Power-Down pin. Is the impedance defined by output resistors + resistor-feedback network?

  • ADA4930 input range at 5V supply

    Can you tell me the input range of ADA4930-1 / ADA4930-2 when it is supplied
    with 5V? Only its common-mode input voltage range is specified as 0.3V to 2.8V.
    What peak value of a superimposed AC signal is allowed for fully differential
  • Using ADA4930-1 with AD9284

    Dear all,

    I have a single-ended unipolar input signal of 0V to 5V (50 ohms source resistance) connected to the non-inverting input of the ADA4930-1.

    The ADA4930-1 is powered by single-supply 5V and has input common-mode voltage range of 0.3V to 2.8V.

  • ADA4930 supply voltage

    Hi,

    I'm pretty new to PCB designs, and in datasheet of high speed differential amplifier ADA4930 , I don't understand what voltage I should supply to this device.

    They say 3,3V or 5V with +Vs and -Vs so I suppose +3,3/-3,3V or +5/-5V ; but in test…

  • RE: ADA4930-1 Single-supply

    Hi Harry,

    Thanks for your support!My customer is designing this part,If ADA4930-1 supply can be 3.3V to 5V,Could you give some feedback?many thanks!

    Best regards
