The MAX7440/MAX7441/MAX7442 six-channel video reconstruction filters replace 30 or more discrete components. The devices are ideal for digital-to-analog converter (DAC) video reconstruction applications, when analog video is reconstructed from a digital data stream. The MAX7440/MAX7441/MAX7442 operate from a single +5V power supply. The inputs are DC-coupled from the DAC and the output can either be AC- or DC-coupled. The DC-IN, DC-OUT architecture leads to a perfect line-time distortion performance (zero tilt). The filters have a cutoff frequency optimized for PAL, NTSC, and SDTV video applications and offer three high-frequency boost options. The MAX7440 offers a flat passband response on all six channels; the MAX7441/MAX7442 offer high-frequency boost on the three channels used for CVBS and Y/C.
The MAX7440/MAX7441/MAX7442 are available in a 14-pin SO package and are fully specified over the extended temperature range.
