MAXIM MAX11501, MAX11502 Technical data

General Description

The MAX11501/MAX11502 integrated filters offer three
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 MAX11501/MAX11502 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 typical -3dB band­width of 8.6MHz (MAX11501) and 8.9MHz (MAX11502)
and offer either a flat passband response (MAX11501)
or a +0.8dB peaking passband response (MAX11502)
on all 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 of below 1V after the back­match resistor.

The MAX11501/MAX11502 operate from a single +5V
supply and are available in the upper commercial 0°C
to +85°C temperature range. These devices are avail­able in small 8-pin SO 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.
