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 typical- ly 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. Applications: Set-Top Boxes, Televisions, Portable Devices
The MAX9583, MAX9584 and MAX9585 are small, low‑power video filter amplifiers designed for standard‑definition video in televisions, set‑top boxes and portable devices. They feature integrated reconstruction filters with ±1 dB passband flatness at 8.5 MHz and 55 dB attenuation at 27 MHz, and provide a fixed gain of 2 V/V.
These devices operate from a single 2.7 V to 3.6 V supply, draw 3.5 mA to 7 mA per channel, and work over an automotive temperature range of –40 °C to +125 °C. They are offered in 6‑pin thin SOT23 (MAX9583), 8‑pin µMAX (MAX9584) and 10‑pin µMAX (MAX9585) packages, supporting DC‑coupled 75 Ω or AC‑coupled 150 Ω video loads.
