Dual, Triple, and Quad Standard-Definition Video
Filter Amplifiers with DC-Coupled Input Buffers
General Description
The MAX9583/MAX9584/MAX9585 are small, low-power,
multichannel video amplifiers with integrated reconstruc-
tion filters. Specially suited for standard-definition video
signals, these devices are ideal for a wide range of
television, set-top box, and portable applications.
The MAX9583/MAX9584/MAX9585 inputs can be
directly connected to the outputs of a video digital-to-
analog converter (DAC). The reconstruction filter typical-
ly has ±1dB passband flatness at 8.5MHz and 55dB
attenuation at 27MHz. The amplifiers have a 2V/V gain
and the outputs can be DC-coupled to a 75Ω load which
is the equivalent of two video loads, or AC-coupled to a
150Ω load.
The MAX9583/MAX9584/MAX9585 operate from a 2.7V to
3.6V single supply and are specified over the -40°C to
+125°C automotive temperature range. The MAX9583 is
offered in a small, 6-pin thin SOT23 package. The
MAX9584 is offered in a small, 8-pin µMAX
®
package,
and the MAX9585 is offered in a small, 10-pin µMAX
package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
