• AD8055

    Hello,

    I am using AD8055 and I am providing +5.5/-2.0 V as supply voltage. I want to know does it affect the performance of the AD8055. Does the rise time and fall time get affected ?

    Also, What is the maximum voltage i can use as an input voltage on…

  • 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…

  • Using AD8055 as a non-inverting op-amp

    Hi there!

    I am using an AD8055 in a circuit. The IC is currently being used as an non-inverting op-amp as in figure 38, page 12, of  the AD8055 's datasheet. The input is from a tuned circuit (inductor and  capacitor in parallel) and is at 200kHz with…

  • 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…

  • 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…

  • 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…

  • RE: Analog output interface for HS-DACs

    At lower frequencies, an op amp can be used to acheive differential-single ended conversion along with some gain if needed. For example, one recommended configuration for the AD9740 is shown below. Suggested op-amps for the interface are AD8055, AD8057…

  • Alternatives to the AD829

    Alternatives to the AD829

     

    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…
  • RE: ADC前段,电压跟随器的选择

    您可以看一下ADA4817, AD8055, AD8057, AD8061以及AD8067这几个器件,压摆率满足您的要求,但请注意他们都不是轨到轨输入以及输出的放大器,要处理0~5V的信号的话,供电正轨要大于5V,负轨要低于0V,具体留多少裕量要参考具体的数据手册。

  • 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…
