• LTC4020 Design - 4S lithium battery

    I'm designing a device which will be employed in cars and trucks, so it must withstand 12V o 30V as an input (battery of the vehicle). Additionally, 4s Li-ion (16.2V) will be placed in our devices as a back-up battery since if he vehicle is turn off,…

  • ADA4084-2

    Hello,

    My understanding from the datasheet provided by Analog Devices is that ADA4084-2AFQMLL and ADA4084-2AFQMLR are the unscreened versions of 5962L1324502VXA and 5962R1324501VXA. Is that correct or am I mistaken?

    Ultimately we are hoping for unscreened…

  • ADA4084 characteristics

    Dear all,  

    I probably posted a message in the wrong forum. Please find below the question related to ADA4084

    Datasheet Table 3 specifies that at +/-5V, typical input impedance is [100KOhms||1.1pF]Differential and [200MOhms||2.5pF]Common mode.

    Are these…

  • ADA4084 SPICE Model

    Hello,

    I'm trying to use ADA4084 spice model inside of LTSpice. 

    However, I'm getting errors "Singular matrix: check node u7:82 Iteration No.1", where u7 is one of the ADA4084 instances. 

    I have read elsewhere online that LTSpice doesn…

  • ADA4084 Settling Time

    Hi,

    -Do you know what does the 0.1% means in the test conditions of settling time ? (see below)

    Settling Time : ts : AV = 10, VIN = 10 V p-p, 0.1%        typ:4µs.

    - I did not understand figure 30, 61,92 of settling time.

    For Figure 92, Vsy=+/-15V, Input…

  • Exposed pad on ADA4084-2

    What's the consequence of leaving the exposed pad unconnected on the ADA4084-2? The datasheet says it must be connected.  Will the result be poor thermal performance or are there other potential issues

  • ADA4084 Minimum Supply Voltage, Single-Supply

    I am simulating both the OP484 and the ADA4084 in the attached LTspice schematic. The circuit provides a linear output voltage as a function of the input voltage. The input voltage also biases the amplifier. I originally assumed I should only specify…

  • Strange Input Current in ADA4084-1

    Greetings.

    I am using the ADA4084-1 in a non-inverting, follower configuration in a data acquisition application.  The input is AC coupled.  At high input power levels, the input suddenly latches to a high value, and will stay there until the input RMS…

  • ADA4084增益带宽积


    在阅读AD4084-2手册中发现其增益带宽积有GBP 和-3dB 两种,而且在GBP中标明Av=100时为15.9MHz,在-3dB中Av=1,却只有13.9MHz。问题如下:

    1.两个增益带宽积概念有什么区别?

    2.在GBP中指明Av=100,是说小信号放大100倍时带宽为15.9MHz吗?

    3.Unit-Gain Crossover 是什么意思?

    4.通常预计带宽余量时倍数为20合适吗?

  • ADA4084-2 Spice Model Weird Noise Behavior

    I am trying to design a ADA4084-2 into my latest design, but I am receiving strange results when I do noise modeling using the Spice circuit.  The voltage noise at the output is extremely large, even with relatively small feedback resistor values.  It almost…
