  • ADA4950-2 Input Current Specification


    I am using ADA4950-2 Differential Amplifier to make  differential my DC signal. I hve a output common mode voltage of 1.5 V for this chip
    I have two questions:

    1) When nothing is connected to INA- and 1.65 V is connected to INA+ I see 1.47 V(apporixmately…

    Attached is the board file for ADA4950-2. The old evaluation board for ADA4950-2 is obsolete and is replaced by EVAL-FDA-2CPZ-24.


  • Sporadic ADA4950 failures

    Hi all,

    I'm using ADA4950-1YCPZ amplifiers as the last stage in a preamp before driving an AD9650.  The ADA4950 is powered by +/-5V supplies.  The unity gain inputs (pins 2 and 3) are driven by ADA4897s powered by the same +/-5V supplies.  Pins 1 and…

  • ada4950-1 vocm problem?


    i want to use ada4950-1 as an single to differential amplifier with the gain of 1 and output common voltage  at  500mv , i used adr130 to produce the 500mv and connected directly its output to the vocm of ada4950.when i power up the board and just  measure…

  • ADA4950-1: temp drift

    Please let me know the temperature-drift SPEC for the gain of ADA4950-1.

    They find that the related curves are shown in Figure 9 and Figure 10 in the
    datasheet. Now they want to get the specific values of the temperature drift.


  • ADA4950-1/ capacitance load query


    We do have a catheter cable length of 2.4 meter , trying to understand if the amplifier ADA4950-1 will be able to drive the same or not?

    We have set this for a gain of 2. The input level from the FPGA is driven as 2.4V p-p, output of the ADA4950-1 is…

  • ADA4950 BW and Vocm Questions for Design

    Can you provide advice for proper design considerations for the following questions:

    1) The signal we're passing is only operating between 20Hz and 15Mhz.  Would reducing the Bandwidth of the device help prevent oscillations, and if so what would…
