• using ADA4522 as instrumentation amplifier

    Hi ,

    I am trying to simulate the ADA4522 Opamp as instrumentation amplifier as given in the datasheet. but It doesn't work.

    Please help.

  • ADA4522-4 CMRR, PSRR

    Hi

    I'm a DFAE in Japan. Our customer would start evaluation of ADA4522-4 and give us a question. According to D/S of ADA4522, CMRR and PSRR in Table 2 and Table 3 are higher than Figure 30 (CMRR), Figure 33(PSRR).  We don't understand the reason. Could…

  • RE: ADA4522 Spice model Input Bias Current Too high

    Hi,

    Select in the LTspice library, ADA4522-1 model and add its symbol on your test circuit.

    If you opt to use the one in the web, download the cir file. To easily use it and associate it in a symbol without problems, add "opamp2" symbol from the library…

  • Pluto - 2 Rx and 2 Tx using MATLAB

    Hi,

    I would like to setup the SDR Pluto to operate in 2 Tx and 2 Rx mode.

    I have followed the steps in the following video : https://www.youtube.com/watch?v=ph0Kv4SgSuI

    However, I am unsure how to setup and control the 2nd transmitter or receiver. 

  • How do I determine the appropriate amount of compensation capacitance using the ADA4522-2 and the AD5556?

  • ADA4522 IVR (input voltage range) ?

    The data sheet for this device indicates a IVR 0V to 28.5V for  Power supply = 30V

    is IVR the max voltage for proper signal ampification?

    i.e. if Vin = 28.5V, for gain = 1 then Vout = 28.5V?

    Please clarify

    Thank you

  • RE: ADA4940-2, issue on creating 2 differential signals around 0V

    Hi, 

    With a bit late, thanks for this suggestion.

    By applying -0.2V to R3, this circuits can convert 0 to 0.4V to a balanced -0.2 to 0.2V .

    It has been checked on the eval board.

  • ADV7611 YCbCr 4:2:2 SDR issue

    I am trying to configure ADV7611 to output 1280x1024 video in 16-bit SDR ITU-R BT.656 4:2:2 Mode 0.

    In free-run mode with blue background I get "0xFF00, 0x0000, 0xFF00, 0x0000..." pixel data, but it is 1280 LLC-period wide DE window between HSyncs…

  • recommended bypass capacitor value for ada4522

    What are the recommended bypass capacitor values for the ADA4522.

    The only thing I see anywhere is 0.1u, located "close" to the power supply pins.

    Is this adequate or would additional capacitors (2.2u, 10u...) improve performance.

  • ADA4522-1 in differential (non-inverting) integrator configuration (railing)

    Hello,
    I have a question regarding the "railing issue" of the ADA4522-1.
    I want to use this opamp as a DC servo for a TIA, see below.

    As mentioned in the datasheet on page 30 the opamp may rail to V+ if the source resistance at the non-inverting…
