MAX9517

The MAX9517/MAX9524 have two single-pole, singlethrow (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 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/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 amplifiers have a gain of 2V/V, and the outputs can be DC-coupled to a load of 75, which is equivalent to two video loads. The outputs can be AC-coupled to a load of 150, which is equivalent to one video load.

The features of MAX9517 can be summarized as (1)integrated reconstruction filter for standard-definition video; (2)9MHz, ±1dB passband; (3)52dB attenuation at 27MHz; (4)dual SPST switches; (5)fixed gain of 2V/V; (6)DC- or AC-coupled output; (7)2.7V to 3.6V single-supply operation.

The absolute maximum ratings of MAX9517 are (1)VDD to GND:-0.3V to +4V; (2)VIDIN to GND: -0.3V to +4V; (3)COM_, NO_ to GND: -0.3V to (VDD + 0.3V); (4)SHDN, IN_ to GND: -0.3V to +4V; (5)VIDOUT short-circuit duration to VDD, GND: Continuous; (6)continuous input current: VIDIN, IN_, SHDN: ±20mA/ COM_, NO_: ±100mA; (7)Peak Current COM_, NO_ (pulsed at 1ms, 10% duty cycle): ±200mA; (8)Continuous Power Dissipation (TA = +70°C)12-Pin TQFN (derate 14.7mW/°C above +70°C): 1177mW; (9)operating temperature range: -40°C to +125°C; (10)junction temperature:+150°C; (11)storage temperature range: -65°C to +150°C; (12)lead temperature (soldering 10s): +300°C.
