    Kristoffer Flores
    Normal 0 false false false MicrosoftInternetExplorer4 Hi Roman, For regular op amps, the minimum gain stability is given for the non-inverting or noise gain configuration, i.e. for inverting gain of -1, the non-inverting gain is...

  • Forum Post: Can fully differential amplifiers with noise figures of up to 13dB be used to drive a high-speed 16-bit ADC without impacting performance?

    DavidT
    Adequacy of noise performance of fully differential amplifiers for driving high-speed 16-bit ADCs can be determined by comparing the noise figure of the amplifier to the noise figure of the 16-bit ADC. The typical noise figure of a high performance 16-bit pipeline ADC is 30dB to 33dB, while that of...

  • Forum Post: I need a fully differential amplifier with a 2V p-p output swing in 6ns, can I use the THS4521?

    DavidT
    If you require 2V peak-to-peak in 6ns, it is possible to use the THS4521 FDA device. The only caveat is that the THS4521 requires a supply voltage of at least +/-1.65V (or 3.3V single-supply) to achieve such performance. Attached are results from testing the THS4521 with a differential input signal...

  • Forum Post: Fully Differential Amplifier, Single Supply Problem compared to Dual Supply

    William Lu61122
    Hello, I'm using a FDA to reject a 2.5V offset of my signal and amplify the signal such that when it goes through a peak detector, it'll be at 5V. When using dual supply, I am able easily achieve this. However, when changing the configuration to a single supply, the signal will clip if...

    audic mickael
    We are using THS6182. As you can see on the schematic, the THS6182 is powered in +- 12V and Bias2 is always to 3v. When we put Bias1 to 0v, amplifier is ON, in low bias mode (cf datasheet). But, when we put Bias1 to 3.2v, the amplifier is still running instead of sleep mode. In the screenshot...

    Hi! In the application note SLVA417 , applying values from Table 2 in the equation (18), the calculated output error due to the input offset voltage is 4 mV. But the total output error showed in Table 2 is 0.4 mV, so it doesn't seem correct to me. Am I missing anything? Thanks in advance. ...
