MAX7430EUB+T

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P21
General Description
The MAX7428/MAX7430/MAX7432A filters are low-cost,
high-performance replacements for standard discrete fil-
ter and buffer solutions. The MAX7428/MAX7430/
MAX7432A are ideal for anti-aliasing and DAC smooth-
ing video applications, when analog video is reconstruct-
ed 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/
MAX7432A 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
MAX7432A triple filter is optimized for component (YP
b
P
r
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 MAX7432A is available in a 14-pin TSSOP
package. The MAX7428/MAX7430/MAX7432A are fully
specified over the -40°C to +85°C extended temperature
range.
