• About AD8055 amplifying video signal

    ALL HI！

    I intend to use AD8055 to transmit ahd camera signal. As shown in the figure below, the input signal drives four wires through ad4055. If I only want to drive one wire, just remove the circuit in the red box as shown in the figure? I also need…

  • AD8055(opamp) - AD9240 (ADC ) - Change in Common mode voltage at ADC input terminals

    Hi,

    We are using AD8055 op amp for a DC coupled application, to drive the AD9240 ADC.

    We have to set the common mode of the inputs as 2.5V. We have implemented a recommended circuit as per the AD9240 recommedation as per below image.

    .

    As per above circuit…

  • AD8055 differential amplifier

    Hello,

    I am using the AD8055 as output stage for the DAC AD9767. As in the DAC Datasheet described, I use it as a differenital amplifier with the same resistor values (page 29 figure 74). I simulated the circuit and the following voltages should be with…

  • How effective can be 3-stage OPAMP solution based on AD8055 for photo diode signal detecting

    Hi all,

    I am currently research about VLC and I developed some photo detector solution based on 2-stage AD8055 as DIP-based 300MHz VFb OPAMP, as I needed to go far beyond ~6MHz that was proposed in solution from AD photo diode wizard,  I modify and tweak…

  • Alternatives to the AD829

    Q 

    Alternatives to the AD829

     

    A 

    I can recommend alternatives though. Other single high speed opamps with
    Bandwidth > 120MHz and Slew rate > 230V/us are

    AD811 Single
    AD818 Single
    AD815 Dual
    AD828 Dual

    You will open up…

  • AD9774: DAC output range and external buffer

    Q 

    I am looking for high speed 14bit DAC (0 to 30MHz) with output voltage swing
    (prefer adjustable)of [-0.5v to 3v].
    Please also advise if  AD9774 DAC can be used with load resistor greater than
    50ohm in order to achieve required output swing.
    May…

  • RE: ADA4432-1 IC as a video receiver amplifier

    The ADA4432 can be use as a video buffer along with other op-amps as long as they have enough bandwidth and you handle any video offset issues.

    The Video signal output from the DAC will always be above ground so the ADA4432 only needs 0-3.3V rails.  To…

  • Switching Output of Operational Amp

    I am using AD8055 as an inverting amplifier in a set-up similar to Fig. 35(I used 1k instead of 402 Ohm).

    What I need to do is switch on/off the output of the amplifier.

    First, I put a switch ADG451 to the output of the op-amp, then it made a huge spike…
