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-coupled 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 8.5MHz and 55dB 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 single 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.
The MAX9586–MAX9589 family are low‑power, multi‑channel video amplifiers with integrated reconstruction filters and input clamps, designed for standard‑definition video in set‑top boxes and televisions. They operate from a single 2.7 V to 3.6 V supply and support both DC‑ and AC‑coupled outputs to 75 Ω or 150 Ω loads.
Key features include a fixed gain of 2 V/V, ±1 dB passband flatness at 8.5 MHz, 55 dB attenuation at 27 MHz, and operation over an automotive temperature range of –40 °C to +125 °C. The family is offered in compact SOT23 and µMAX packages.
