General Description
The MAX4188/MAX4189/MAX4190 are low-power,
current-feedback video amplifiers featuring fast dis-
able/enable times and low switching transients. The
triple MAX4188 and the single MAX4190 are optimized
for applications with closed-loop gains of +2V/V (6dB)
or greater and provide a -3dB bandwidth of 200MHz
and 185MHz, respectively. The triple MAX4189 is opti-
mized for closed-loop applications with gains of +1V/V
(0dB) or greater and provides a 250MHz -3dB band-
width. These amplifiers feature 0.1dB gain flatness up to
80MHz with differential gain and phase errors of 0.03%
and 0.05°. These features make the MAX4188 family
ideal for video applications.
The MAX4188/MAX4189/MAX4190 operate from a +5V
single supply or from ±2.25V to ±5.5V dual supplies.
These amplifiers consume only 1.5mA per amplifier and
are capable of delivering ±55mA of output current, making
them ideal for portable and battery-powered equipment.
The MAX4188/MAX4189/MAX4190 have a high-speed
disable/enable mode that isolates the inputs, places the
outputs in a high-impedance state, and reduces the
supply current to 450µA per amplifier. Each amplifier
can be disabled independently. High off isolation, low
switching transient, and fast enable/disable times
(120ns/35ns) allow these amplifiers to be used in a
wide range of multiplexer applications. A settling time
of 22ns to 0.1%, a slew rate of up to 350V/µs, and low
distortion make these devices useful in many general-
purpose, high-speed applications.
The MAX4188/MAX4189 are available in a tiny 16-pin
QSOP package, and the MAX4190 is available in a
space-saving 8-pin µMAX
®
package.
