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 7MHz and 40dB 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.
