_______________Detailed Description
The MAX4112/MAX4117/MAX4119 are optimized for
closed-loop gains (AVCL) of 2V/V or greater, while the
MAX4113/MAX4118/MAX4120 are optimized for
closed-loop gains of 8V/V or greater. These low-power,
high-speed, current feedback amplifiers operate from
±5V supplies. They are designed to drive video loads
with low distortion characteristics. The MAX4112/
MAX4117/MAX4119’s differential gain and phase are
0.02% and 0.03°, respectively; the MAX4113/
MAX4118/MAX4120 exhibit gain/phase error specifica-
tions of 0.02% and 0.04°, respectively. These charac-
teristics, plus a wide 0.1dB gain flatness, make the
MAX4112/MAX4113/MAX4117–MAX4120 ideal for use
in broadcast and graphics video systems. The combi-
nation of ultra-high speed and low power makes these
parts suitable for use in general-purpose, high-speed
applications, such as medical imaging, industrial instru-
mentation, and communications systems.
__________Applications Information
Theory of Operation
Since these devices are current-feedback amplifiers,
their open-loop transfer function is expressed as a
transimpedance, VOUT/IIN, or ZOL. The frequency
behavior of the open-loop transimpedance is similar to
the open-loop gain of a voltage feedback amplifier.
That is, it has a large DC value and decreases at
approximately 6dB per octave.
Analyzing the follower with gain, as shown in Figure 1,
yields the following transfer function:
where G = AVCL = 1 + (RF / RG), and RIN = 1 /gM 30.
