    Q 

    The ADA4807 is featured as a high speed performance amplifier. Can I use it in
    audio applications?

     

    A 

    Yes. The ADA4807 is a low noise, low distortion amplifier. The low 1/f voltage
    noise corner of 29Hz, the low distortion of -139dBc THD…

  • 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…

  • RE: ADA4807-2 become very heat when it put-in a ±5v circuit?where is  the reason?

    1. the device（ADA4807） will reach 100℃ after  about 10 second.

    2. The schematic as follow.

  • 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?

    Q 

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

     

    A 

    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…

  • Ada4807 analysis

    I created a lt spice model of my circuit which consists of an op amp in a unity gain voltage follower configuration which feeds a SAR ADC. I also included the flywheel circuit in front of the adc. There are two models, each one having a different op amp…

  • ADA4807-4 IBIS Model

    Saludos. En este momento estoy trabajando con el amplificador ADA4807-4 (www.analog.com/.../ada4807-4.html), y necesito realizar análisis de integridad de la señal (SI), pero no puedo encontrar el modelo IBIS de este amplificador. ¿Alguien…

  • 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?

  • What type of converters can the ADA4807 drive?

    Q 

    What type of converters can the ADA4807 drive?

     

    A 

    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…
