MAX9586

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-coupled to the inputs of the MAX9586-MAX9589. The MAX9586-MAX9589 operate from a 2.7V to 3.6V single supply and are specified over the -40°C to +125°C automotive temperature range. The MAX9586-MAX9589 are offered in small SOT23 and MAXpackages. The amplifiers have 2V/V gain and the outputs can be DCcoupled to a 75load, which is the equivalent of two video loads, or AC-coupled to a 150load. The MAX9586MAX9589 are small, low-power, multichannel video amplifiers with integrated reconstruction filters and input clamps. Specially suited for standarddefinition video signals, these devices are ideal for a wide range of television and set-top box applications. 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.
