General Description
The MAX11504/MAX11505 integrated filters offer four
channels of 5th order filters for standard-definition video
and include +6dB output buffers on each channel. These
video filters are ideal for anti-aliasing and DAC smoothing in applications such as set-top boxes, security systems, digital video recorders (DVRs), DVD players, and
personal video recorders.
The MAX11504/MAX11505 video inputs feature a transparent clamp compatible with AC- and DC-coupled
input signals and allow DAC outputs to be directly coupled. The 5th order filters provide a bandwidth of
8.6MHz (typical). The MAX11504 offers a flat passband
response on all channels. The MAX11505 offers a 0.8dB
peaking passband response on Channel 1, resulting in
a bandwidth of 8.9MHz (typical) and a flat passband
response on all other channels.
Each channel includes an output buffer with a gain of
+6dB capable of driving a full 2V
P-P
video signal into two
standard 150Ω (75Ω back terminated) video loads. The
buffers drive either AC- or DC-coupled loads and assure
a blanking level below 1V after the back-match resistor.
The MAX11504/MAX11505 operate from a single +5V
supply and are available in the 0°C to +70°C commercial temperature range. These devices are available in
small 10-pin µMAX
®
packages.

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.
