FAQ
Hello,
I would like to use the AD8009 to drive a variable capacitive load over a SMA cable.
According to the datasheet, I need to "insert a resistor in series between the op amp output and the capacitor." It is required to "to prevent instability and…
您好:
我希望放大一个500uv的1PPS方波,需要比较好的上升沿和下降沿性能,选用了AD8009,放大了300倍,测试后发现电压被抬高很多,是否是Vos引起的?
阅读相关帖子,我现在觉得我的设计有以下问题:
1.500uv作为小信号应该侧重考虑GBP
2.我关注输入和输出的上升沿偏差值的稳定性是否侧重考虑的Vos的温度漂移
3.放大倍数过高,降低了上升沿性能
想咨询一下:
是否应调整为两级放大,减少放大倍数
是否有能兼顾GBP和Vos的放大芯片或设计
电路设计时有没有能对上升沿速度和上升沿稳…
Hi everybody,
I am planning to build a circuit to get the maximum of the signal as in this paper.

I want to replace LTC6244 with AD8009.
I want to ask if AD8009 is suitable…
Hi
I'm a DFAE in Japan. Our customer is interested in AD8009 and gives us a question as follows.
Some TPCs do not have measurement conditions. Could you tell me about them? Especially he wants to know about TPC 10.

Hi
I am using a AD8009 OPAMP along with AD834 DDS based circuit with -4.4V to +4.4V supply, at these case AD8009 is extremely heating up and it is giving output as well, what causes to heating up the AD8009 ?
I´m designing a LVCMOS to NIM signal translator, requirements of the circuit are
Input frequency from 10KHz to 40Mhz
Input 3.3V LVCMOS
Output logic "0" 0mA or 0V; logic "1" 18mA or 1V
I decide to use AD8009 because it declares…
There Folks
I designed an input, output AC Coupled amplifier by AD8009. output ac couple circuit has a 47u capacitor.
are there any issues for ad8009 to working with this cap value as an output ac coupling?

I am tring to build an amplifier circuit by using AD8009 with its single power supply. However, when I applied +10V to VS+ and GND to VS-, it seems the amplifier didn't work. The output current of my digital power supplier is about 0. Can someone help…
