• ADA4927 Power Down Pin

    Hello, I have a question about this feature, in the data sheet says:

    The power-down feature can reduce power consumption when a particular device is not in use and does not place the output in a high-Z state when asserted. The ADA4927 is generally enabled…

  • RE: ADA4927-x : Power Down control in cold temperature

    Hello Andy-san,

    I'm sorry, I have no more information about the ambient temperature of ADA4927-x.
    But I am interested in your information because I introduce ADA4927-x for the customer who needs a highspeed amplifier.
    Is that a quality issue?

  • 给运放(ADA4807+ADA4927)供电的正负电源上电启动失败

    设计的一块多通道模拟信号电路板,ADC前端有16路模拟通道,每个通道有1片ADA4807-2ARMZ和一片ADA4927,都是正负5V供电。供电方案如下:

    正电源: LTM4644(12V转5.5V)+TPS7A8400(LDO 5.5V转5V)

    负电源:ADP5074(12V转-5.5V)+LT3091MPDE(LDO,-5.5V转-5V)

    电源没有做上电顺序控制,上电之后默认都开始工作。

    启动失败的现象是:

    1. 上电之后,测量运发昂的供电电压,正电源输出+5V,正常;负电源输出不正常,一般是…

  • Harmonic distortion for ADA4927-1 in single-ended output configuration

    Hi,

    I need to convert the differential signal to the single-ended (SE) signal. The harmonics level at frequencies of DC-180 MHz shall not exceed -45 dBc when the signal level 0.56 Vp-p. Matching differential receivers I have not found. Use a differential…

  • ADA4927 - minimum Rf resistance value

    Hi!

    ADA4927, as a current-feedback amplifier, most likely does not tolerate too low values of Rf resistor (between output and inverting input), however I cannot find this information in the datasheet.

    I would like to use it in an application of I/V converter…

  • ADA4927-2 Layout suggestion

    I am going to design a pcb with the ADA4927-2 OpAmp, so i would ask for a good layout example or suggestion.

    Are there any evalboard-files or something to see a good layout example for this opamp?

    Best Regards
