• ADA4075-2 and SSM2167 Q's

    Hi,

    We are looking at using the ADA4075-2 instead of the OP275, as recommended by ADI, as a balanced line driver to the AD1974. However, the reference design uses trimpots whereas these are not shown for the OP275 reference design. As we are looking…

  • RE: ADA4075-2 Input Supply

    Hi Prachi,

    I apologize for the delay in my response. The ADA4075-2, powered by +5V and referenced to +2.5V, should be able to reproduce a 1 Vp-p signal with no trouble.

    Best regards,

    Coleman

  • ADA4075-2 PSRR decreasing during operation?!

    Hello,

    I have got an amplifier which is working pretty well with ADA4004-2, OP284 & AD8599 Low Noise OA's.

    Please see schematic attached, it has two +/-5V supply lines.

    ADA4075-2 is 3-4 times cheaper, so it is more attractive on that reason

  • popcorn noise in some ADA4075-2 devices?

    For a low noise dual opamp I selected the ADA4075-2 based on the datasheet "typical" spec of 60 nVpp noise at f = 0.1 Hz to 10 Hz.  There is no worst-case spec on the data sheet.

    The analog.com site features an article by James Bryant which makes…

  • ADA4075 Differential Input Voltage


    I want to use ADA4075 for a differential input that could have a maximum of 10V differential voltage.

    In the datasheet, I see the absolute maximum rating for Differential Input Voltage is ±1.2 V

    What does this mean? The Inputs should have a difference…

  • Wrong balanced line receiver information in ADA4075 data sheet

    On page 19 of the ADA4075-2 data sheet, there is a circuit called "Balanced Line Driver.

    The whole page is one big wrong thing.

    The first thing that caught my eye is the equation for (high degree of CMRR). When plugging the values of R1, R2, R3…

  • ADA4075在使用过程中出现有时无声、有时有声现象

    ADA4075在使用过程中出现有时无声、有时有声现象

    ADA4075在使用中出现了类似受潮的现象,温度高时芯片正常工作,温度低时会出现无声。但是芯片本身防潮等级MSL1,实际储存中也不存在高潮湿度的情况?还有什么情况会导致芯片损坏?

    无声时芯片输出有正负4V左右的直流偏置,电源供应都正常。无声现象跟随芯片出现。

  • JPEG Processing - 4:2:2 v 4:2:0?

    My JPEG saga continue...

    I am using a BF561 single core to compress a 640x480 YUV 4:2:2 image into JPEG format, employing the ADI JPEG Library tools.  I am getting very poor performance compared with the reference results from the Spec Sheet.  The Spec…

  • ADV7842 4:2:2 DDR mode, ADV7393: Stanag3350 support?  (2)

    Hello Dave,

    I am facing problems with replies to your answer, so I am oppening a new dicussion with the same title.

    Please clarify your answer regarding STANAG support:

    2) As I understand it, this is the same as RS-343A/EIA-343A and none of our parts…

  • LTC6804-2 and LTC6811-2 reference voltage 1 and 2 at 0V.

    Hello,

    I installed 2x LTC6811-2 and then 1x LTC6804-2 on the same board and I don't have any voltage reference output at anytime. The functional diagram in the datasheets shows that VREF1 should be always present as it's generated from V+. VREF2 is not…
