• Problem of PCB layout  of  ADA4899-1

    Hi all,

      It is suggested  in the datasheet of ADA4899 that all ground and power planes under the pins of the ADA4899-1 should be cleared of copper to prevent the formation of parasitic capacitance between the input pins to ground and the output pins to…

  • ADA4899-1输入保护问题

    读ADA4899-1的datasheet,输入端有二极管保护,而Absolute maximum ratings里面,说输入差分电压是±1.2V,这种情况还需要在外部加限压吗?应该是靠内部二极管保护就可以了吧?输入脉冲电压,幅度随机,一般在1V以内,少数可能达到3V以上。±3.3V供电。偶尔出现运放失效的情况。

  • ADA4899-1


    I was wondering if anybody could give us THD frequency sweeps in the audio band 20-20Khz of the ADA4899-1 with gain set to 1. I was wondering if its THD performance was better than the AD797. I would like to use this device in I/V stage of a high…

  • Noise model of ADA4899-1 for LTspice

    When doing a noise analysis in Spice (LTSpice) using the model provided for the
    ADA-4899, the noise output is orders of magnitude larger than specified in the

    At first glance it seems like a noise current of ~12 nA/√Hz is flowing out…

  • RE: Question regarding ADA4899-1

    Hi Richard,

    Good Day!

    1. If you noticed most of our SOIC package High Speed Amplifiers pin outs, pin 5 was allocated as NC or No Connect. Take ADA4857-1 as an example.

    The difference between ADA4899-1 and other HS amplifiers is the modified pin-outs…

  • AD8099 ADA4899-1... mux them together


    I'm using 2 AD8099 (G=20) and 2 ADA4899-1 (G=1), all four are muxed to drive a AD8331...

    The circuit should be very low noise and the Bandwidth around 30MHz.

    I'm wondering how many others AD8099 can I add, without degrading performance?…
