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…
