• AD8376 vs. ADL5202

    Hi.  I would like to use a VGA to drive a AD9434-500 ADC.  The input signal is broadband with relevant content between 5 MHz and 250 MHz.  The AD8376 datasheet describes a resistor output bias method for broadband applications.  Does the ADL5202 also require…

  • AD8376 Load Impedance

    Hello,

    My customer has the following question. Can you advise if the 50 Ohms load impedance would be sufficient for his application?

    On page 15 of the data sheet, it says: "Whereas the gain of the AD8376 is load dependent, RL in parallel with R1 + R2…

  • AD8376 Filter Matching

    Hi, actually I'm working in an interface between the ADL5380 and the AD8376 chip. The ADL5380 specfifies that using a high impedance load like for example 500 Ohm you'll get some  extra gain.

    The AD8376 has internal termination of 150 Ohm differential…

    Hi all,

    at the moment I am busy designing in AD8376 digital controlled VGA in our application. We want to use this OP in an broad band application which mean a frequency range range between some kHz up to 35 MHz.

    When studying datasheet I found some…

  • AD8376的阻抗匹配问题

    请问下ADI的技术人员,AD8376在使用时哪些情况下需要进行阻抗匹配?如果AD8376的输入是由前级运放的输出提供的,并且前级运放的输出和AD8376的输入之间的连线很短,需不需要进行阻抗匹配?

  • AD8376 or AD83875 output bias current

    Hello together,

    at the moment we are busy designing a broad band receiver whith the follwowing input specifications:

    To adjust the receveier to the incomming signal we have decided to cascade ther stages of…

  • FAQ: Operation of AD8375 and AD8376 Digitally Controlled VGAs at Low Frequency

    Q.

    The frequency response plots in the AD8376 and AD8376 DGA data sheets show roll-off at low frequency. Is there any way around this?
