  • Forum Post: Re: Variable Gain Amplifier

    Neil Albaugh
    Let me reiterate-- adding gain switches to high bandwidth current feedback op amps is fraught with peril. Added parasitic capacitance on input nodes will very likely cause instability and oscillation even if the recommended gain resistors are used. If you still wish to proceed, try using a very small...

  • Forum Post: Bandwidth of current feedback amplifiers

    Jason Ensher
    I'm trying to understand the bandwidth and gain tradeoffs of the current feedback amplifiers. I've read a number of application notes, such as slva051, and the application details in datasheets for CFBs such as the OPA695 or even the THS family. They all indicate that the bandwidth of the amplifier...

  • Forum Post: Re: LMH6554* NOISE

    Hooman Hashemi
    The datasheet value of input referred noise voltage and noise current are measured results using the circuit of Fig. 6 and include the noise contribution of VCM common mode path, if any: It is expected that the voltage applied to the VCM input is capacitively decoupled (low pass filtered,...

  • Forum Post: Ringing THS3202

    Mathieu Stephan
    Hello everyone, I'm having an usual problem with the THS3202. If you look at my schematics here: (Please visit the site to view this file) You'll see that I'm cascading 2 THS3202, one with a total gain of 25 (2 times 5) and another with a gain of 5 (5x gain + follower). If I connect...
