Dual, Triple, and Quad Standard-Definition Video Filter Amplifiers with DC-Coupled Input Buffers

The MAX9583/MAX9584/MAX9585 are small, low-power, multichannel video amplifiers with integrated reconstruction 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 typically 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.
