Single, Dual, Triple, and Quad Standard-Definition
Video Filter Amplifiers with AC-Coupled Input Buffers
General Description
The MAX9586–MAX9589 are small, low-power, multi-
channel video amplifiers with integrated reconstruction
filters and input clamps. Specially suited for standard-
definition video signals, these devices are ideal for a
wide range of television and set-top box applications.
The video signals from the outputs of a digital-to-analog
converter (DAC) are AC-coupled to the inputs of the
MAX9586–MAX9589. External video signals, in which
the DC bias is usually not known, can also be AC-cou-
pled to the inputs of the MAX9586–MAX9589. The input
sync-tip clamps set the DC level of composite video or
luma signals, and the input bias circuits set the DC
level of chroma signals.
The reconstruction filter typically has ±1dB passband
flatness at 8.5MHz and 55dB attenuation at 27MHz. The
amplifiers have 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 MAX9586–MAX9589 operate from a 2.7V to 3.6V sin-
gle supply and are specified over the -40°C to +125°C
automotive temperature range. The MAX9586–MAX9589
are offered in small SOT23 and µMAX
®
packages.

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.
