• Connect NC pin 8 to ground on AD8009

    Hello,

    I would like to use the AD8009 in a product to replace an exiting component. The original design had pin 8 connected to ground because it was a CHIP ENABLE pin. Pin 8 in the AD8009 is a NOT CONNECT. Can I safely connect pin 8 on the AD8009 to ground…

  • AD8009: Rail-to-rail

    Q 

    I am using the AD 8009 because of its high speed and broadband functions. My
    problem is, that output voltage swing is too small with -3.9 to 3.9 V at
    bipolar supply. Is there a way to connect two of them maybe in parallel with
    perhaps…

  • AD8009 to drive a variable capacitive load

    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…

  • 用AD8009放大500uv的方波，电压抬升

    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…

  • AD8009 TPC

    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.

  • AD8009 Heating up

    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 ?

  • AD8009 capacitive load drive capability

    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?
