• On the current consumption of the ADA4807-2

    Hi,

    I would like to ask about the current consumption of ADA 4807-2.

    Does this IC change current consumption depending on the input frequency?
    If it changes, I want a simple characteristic graph.

    <conditions>
    ± VS = ± 5 V

    Gain=×5
    Input waveform…

  • 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…

    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.

  • RE: ADC LTC2512-24 Driver Inquiry

    There are advantages to both op amps. You do not specify what you are interested in doing. The primary advantage of the LT6202 is low noise. The ADA4807-2 has lower offset and input bias current, more bandwidth and lower supply current. The LT6203 is…

  • The spec table states the capacitive load drive of the ADA4807-2 is 15pF. Can the ADA4807-2 drive larger capacitor loads? Will this heavy capacitive load make the amplifier unstable?

    The spec table states the capacitive load drive of the ADA4807-2 is 15pF. Can
    the ADA4807-2 drive larger capacitor loads? Will this heavy capacitive load

    Yes, the ADA4807-2 can drive larger capacitor loads…
  • 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…
