The MAX9517/MAX9524 are low-power video amplifiers with integrated reconstruction filters. Specially suited for standard-definition video signals, such as composite and luma, these devices are ideal for a wide range of applications such as cell phones and security/CCTV cameras. Video signals should be DC-coupled into the MAX9517 input and AC-coupled into the MAX9524 input. The MAX9517/MAX9524 have two single-pole, single-throw (SPST) analog switches that can be used to route stereo audio, video, or digital signals. The reconstruction filter typically has ±1dB passband flatness at 9MHz and 52dB attenuation at 27MHz. The amplifiers have a gain of 2V/V, and the outputs can be DC-coupled to a load of 75Ω, which is equivalent to two video loads. The outputs can be AC-coupled to a load of 150Ω, which is equivalent to one video load. The MAX9517/MAX9524 operate from a 2.7V to 3.6V single supply and are specified over the -40°C to +125°C automotive temperature range. The MAX9517/MAX9524 are available in a small 12-pin TQFN (3mm x 3mm) package.
The MAX9517 and MAX9524 are low‑power video filter amplifiers with integrated reconstruction filters for standard‑definition video signals such as composite and luma. They feature a fixed gain of 2 V/V, dual SPST analog switches, and can operate from a single 2.7 V to 3.6 V supply.
The devices are supplied in a 12‑pin thin‑QFN package and are rated for an operating temperature range of –40 °C to +125 °C. Detailed electrical characteristics include supply‑voltage rejection, input resistance, on‑resistance, and crosstalk performance, all documented in the datasheet.
