Hi,
I had designed a non-inverting amplifier by ADA4807-1, following picture is the simulation result of LTspice , 
I used actual IC to verify on the PCB, but the output waveform of ADA4807-1 is 13.26MHz Oscillation waveform. My schematic of PCB is the same…
Hi Fdelaram, i also had contacted customer support. basicly there is an error with the simulation model, will be fix soon.
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…
我选择ADA4807-1和ADA4807-4实现了数个滤波器电路和同向放大电路，但是我发现在每一个电路的输出都存在直流偏置，换成其他芯片（比如AD4096）这个偏置就会消失。请各位大牛帮我分析一下这个问题，感谢！
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…
Good Day,
I have a question about decoupling and bypass capacitors for ada4807. In datasheet its written one is ceramic and the other in parallel is tantalum. The question is can i use both ceramic caps instead of this tantalum or tantalum is necessary…
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…
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?
