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 62dB 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.
