Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX7443/MAX7444 are low-cost, triple-channel ideo reconstruction filters for S-video and CVBS video ignals. These devices are ideal for anti-aliasing and AC smoothing video applications such as set-top oxes, DVD players, hard-disk recorders (HDRs), and ersonal video recorders. These filters MAX7444 operate from a ingle +5V supply. MAX7444 are optimized for NTSC, PAL, nd standard-definition digital TV (SDTV) video systems.

Each channel of MAX7444 consists of a lowpass filter and an djustable-gain output buffer capable of driving two tandard 150 video loads. The output buffers can drive ither an AC or a DC load such that the blanking level oltage after the backmatch resistor is less than 1V. The and C video inputs of MAX7444 are summed to produce the composite ideo output. The MAX7444 offers highfrequency oost to improve picture sharpness. The AX7443 has a maximum flat-frequency  esponse.

The MAX7443/MAX7444 are available in a tiny 8-pin thin FN and an 8-pin SO package with exposed pad, and re fully specified over the -40°C to +85°C extended emperature range.
