• AD8039 noise issue

    In this project, we used Linear's high speed ADC LTC2175, LT6409(SE~Difference) as the driver. AD8039 as the first level amplifier and follower. Signal input Range: ±0.5V~±5V (i.e. Gain: 1~10); Input Freq: DC~60 MHz; When the input signal of AD8039 connected…

  • AD8039 Single Power Supply

    Hi

    AD8039 can work with a single power supply? 

    According to its data sheet, the supply range is 3V to 12V but my AD8039 output 1V under 0V input and 5V single power supply condition. It works correctly (output=0V) by changing +/- 5V supply.

    Regards…

  • AD8039 Absolute Maximum Ratings - Differential Input Voltage

    I have problem with Absolute Maximum Ratings of AD8039. The Differential Input Voltage is limited to +-4V.

    May I apply a slightly higher voltage if I limit the current with the series resistor?

     

     

    In my circuit I have ADA4897 Rail-to-Rail output amplifier…

  • Phase reverse protection AD8039/AD8099

    AD8039 and AD8099 do have phase reverse protection?

     

    Thank you.

    怀疑AD8039是否已被损坏。换芯片试试？

  • RE: Practical OpAmp filter based on Filter Wizard design not working

    Harry,

    Highest signal frequency 140KHz.

    AD8039 is specified by Filter Wizard tool.

    Layout follows recommendations in AD8039 data sheet.

    If necessary I will deal with any instability issues later.

    My main concern now is the DC levels. I was expecting…

  • AD8039 Minimum Output Swing

    Q 

    What is the minimum output swing, the datashet only gives the typical outut
    swing?

     

    A 

    The worst case output saturation is 1.1v, that is, the output worse case will
    swing 1.1V to 3.9V.  This is a 6 sigma statistic that is for both process…

  • Any other OPAMPs as voltage reference instead of AD8031?

    Hi all:

    I'm using the Filter Wizard tool: Filter Wizard | Analog Devices to design a high pass filter, my amp is single power supplied, and the wizard adds a reference voltage generation circuit using AD8031.

    Click "What's this" and it says:…

  • Differential Driver Topology

    Hello

    I am confused and I don't what to do, so I decided to ask the experts: what topology sholud I use to drive the inputs of a differential line driver

    (in particular AD8132)?

    Here are some details: I have a single-ended signal source which…
