The MAX7428/MAX7430/MAX7432 filters are low-cost,
high-performance replacements for standard discrete fil-
ter 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 sin-
gle +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 (YP
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 pack-
age, 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.
