The MAX7428/MAX7430/MAX7432 filters are low-cost, high-performance replacements for standard discrete filter and buffer solutions. The MAX7428/MAX7430/MAX7432 are ideal for anti-aliasing and DAC smoothing video applications, when analog video is reconstructed from a digital data stream. These devices require a single +5V supply and the filters have a cutoff frequency optimized for NTSC, PAL, and standard definition digital TV (SDTV) video signals. The MAX7428/MAX7430/MAX7432 feature Maxim's Single Pin Bus (MSPB™) interface to digitally control channel selection (IN_A or IN_B), adjust high-frequency boost, bypass the filter, configure luma vs. chroma operation, and control the output disable. The MAX7428 single-channel filter is ideal for composite (CVBS) video signals. The MAX7430 dual filter is optimized for S-Video (Y/C) applications. The MAX7432 triple filter is optimized for component (YPbPr or embedded synchronous RGB) video signals. The MAX7428 is available in a tiny 8-pin SOT23 package, the MAX7430 is available in a miniature 10-pin µMAX® package, and the MAX7432 is available in a 14-pin TSSOP package. The MAX7428/MAX7430/MAX7432 are fully specified over the -40°C to +85°C extended temperature range.
