  • RE: CMOS AMP contains no BJT

    Hi Alexey,

    Good luck with your application.

    Please do consider that the gain bandwidth product of AD8656 is 27 MHz and AD8652 is 50 MHz. The choice of amplifier will depend on your signal frequency and the gain you need to implement. I'm looking forward…

  • RE: Current noise details for AD8647

    Hi ,

    We are looking at this device for low cost TIA application and according the specification we see that other parameter matches our specs and only thing needed the current noise details .

    And we are also looking at AD8616 and AD8652

    Thanking …

  • RE: composite amplifier

    Hi Sampath,

    I suggest you can use the AD8651/AD8652 part. AD8651/AD8652 has a bandwidth of 50 MHz at 5V supply, has low noise density of 4.5 nV/√Hz at 100 kHz, has a typical offset voltage of 100 uV and slew rate of 41 V/μs. You can download its datasheet…

  • RE: Can DC890B evaluation board interfaced in any way other than using QuikEval or PScope?

    Mr. Hoover

    Actually, input bias current is another criteria for our application(tens of nano Amp or less is allowable), so that is the reason why I thought AD8652 or AD8618 will work for my application. As per your recommendation, ADA4807-2 is great…

  • Noise optimizing AD8599 &&

    Good day,

    I have a task to optimize noise in BW 10Hz - 10kHz.

    Voltage gain shall be around 20..50. OA connected directly to source of signal,

    which has impedance 1kOm DC and 50Om AC. OA connected to middle point of R1/R2 divider,

    where R1 connected…

  • RE: 【求助】ADMP401 加运放ADA4897-1 电路  Vref取值问题?


    REF的值主要取决于后端运放的供电范围以及要放大的信号增益。具体计算可以参考ADI应用笔记AN1165  Supply Voltage一节。
