    Active Filtering With the THS4211

    converter. The first circuit performs a differential to
    single-ended conversion with the THS4211 con-
    figured as a difference amplifier. The difference
    amplifier can double as the termination mechanism
    for the DAC outputs as well.

    Figure 78. A Linear, Low Noise, High Gain
    ADC Preamplifier
    For cases where a differential signaling path is
    desirable, a pair of THS4211 amplifiers can be used
    as output buffers. The circuit depicts differential drive
    into a mixer's IF inputs, coupled with additional signal
    gain and filtering.
    The second circuit depicts single-ended ADC drive.
    While not recommended for optimum performance
    using converters with differential inputs, satisfactory

    Figure 79. Driving an ADC With a
    Single-Ended Input
    High-frequency active filtering with the THS4211 is
    achievable due to the amplifier's high slew-rate, wide
    bandwidth, and voltage feedback architecture. Sev-
    eral options are available for high-pass, low-pass,
    bandpass, and bandstop filters of varying orders. A
    simple two-pole low pass filter is presented here as
    an example, with two poles at 100 MHz.
    Two example circuits are presented here showing the
    THS4211 buffering the output of a digital-to-analog
