  • AD8306: Time constant required for the dc-offset

    Q 

    The AD8306 datasheet  mentions a "special dc-offset sensing cell" (page 7) to
    null residual input offset. For our fast optical range finding application I
    would be interested in the time constant (response time) of this dc-offset…

  • AD8306存在自激振荡现象，什么原因？

    如题，AD8306应用限幅输出端口LMHI、LMLO，当输入信号较小或者无输入信号时，存在自激振荡现象，输出端存在500M左右的正弦信号；当将输入端短接同样会有这个现象。当输入信号较大时，不会出现震荡现象，可以正常放大信号，请教这个问题，谢谢！！（内部原理图如下：）

  • AD8306 Logarithmic Amplifier Noise

    Hi,

    I'm analyzing the signal to noise ratio of a system which includes an AD8306. I'm using the logarithmic amplifier output VLOG, and I'm interested in the noise contribution og the RSSI path. So basically I'm interested in the SNR as a function of…

  • AD8306 optimum working frequency

    Hello, if You look at picture n°8 in the datasheet (rev A) of AD8306, it appears that the best working frequency should be somewhere around 100 MHz.

    Have You tested this device at more diffrerent closer frequencies around 100 MHz (for instance, 85, 90…

  • Can AD8306 be used as an AGC amplifier

    Hello,

       I'm a bit confused about AD8306.Can this chip control the output amplitude?Can it be used as an AGC amplifier?

       Thanks!

  • The AD8306 datasheet claims an extra 18dB gain using the programmable output stage.  Will 100 dB dynamic range be achieved with evaluation board, or are external components needed?

    I'm interested in simply an RF input and measure Vout to -80 dBm sensitivity.  Will this be achieved with eval board.  What's the typical configuration for highest dynamic range?  Thanks

  • AD8306, AD8309 limiting amplifier initial phase delay, pulsed RF

    Can the AD8306, AD8309 limiting amplifier initial phase delay can be estimated, with an input RF pulse applied. In other words, would the limiter phase response traverse the same phase plot, even though the input power is changing rapidly?
