• ADA4807-4 IBIS model

    regards. At the moment I am working with the ADA4807-4 amplifier ( www.analog.com/.../ada4807-4.html ), and I need to performing Signal Integrity (SI) analyses, but I can not find the IBIS model of this amplifier. Can someone help me?

  • RE: ADA4807-4替换ADA4851-4

    谢谢您的回复,恩,我这边是5v供电的,输出摆幅为2.5Vpp就行,应该可以替换的,根据手册上的噪声数据,应该还是ADA4807-4好点。

  • ADA4807

    We are using the amplifier ADA4807-2 as an integrator. The ADA4807 is powerd from 6V. As an integrator the output is saturated to the rails. In our circuit it seems that the current consumption without any load increases with a few milliammperes when…

    Dear Analog Devices

     

     

     

    I am having challenge in understanding the datasheet on the ADA4807 (alternative AD8027), in respect of the output swing.

     

    My challenge is that I have an input from a potmeter, providing a voltage input to a “buffer…

  • ADA4807-4放大输出1.3M正弦波时有稳定频率为21Mhz的噪声以及42M,63M的谐波。

    示波器上对信号做FFT分析,发现噪声稳定而且幅度不小,主要就是21Mhz及其2,3次谐波。

    芯片的4运放,均设计的是同相放大2倍电路,输入信号由信号发生器给出的1.3Mhz,峰峰值1V,无直流偏置的的正弦波。

    一个一个运放测试,输出结果都一样。不明白噪声源从何而来,而且这么固定。

  • ADA4807 Spice Model Slew Rate Modeled Correctly?

    Hello,

    I am using the ADA4807 model to model the ADA4807-2 in an active filter application where the output is a 10 MHz sinewave. The output has a peak voltage of 1.79 V.

    Theoretical calculation shows:

    Min Req Slew Rate = 2 * pi * 10 * f * Vpeak/(10…

  • Why is it important to use the ADA4807 as a reference buffer?

    Why is it important to use the ADA4807 as a reference buffer?

     

    The reference input on a SAR ADC represents a dynamic load. The ADA4807
    provides a low impedance, low noise driver that is required to keep the
    reference voltage low noise…
  • RE: ADA4807-2 become very heat when it put-in a ±5v circuit?where is  the reason?

    Thank You for your reply.

    I don't give input signal, I just solder ADA4807 on the PCB, and I have try another ADA4807, but all of them generate heat . 

    when I use AD8671 or ADA4841, they are normal. they have same the define of Pin.

  • What type of converters can the ADA4807 drive?

    What type of converters can the ADA4807 drive?

     

    The low broadband noise of 3.1nV/rHz and the low distortion of -139dBc makes
    the ADA4807 an ideal option for driving 16 and 18 bit SAR converters such as
    the AD7980, AD7685/AD7686 and the…
