Each channel of the MAX11504/MAX11505 contains a
transparent input clamp, a 5th order lowpass filter, and
an output amplifier with +6dB gain (see the Functional
Diagrams and Typical Operating Circuits ). The 5th order
lowpass filters provide a bandwidth of 8.6MHz (typical).
The MAX11504 provides a flat passband response. The
MAX11505 features a 0.8dB high-frequency boost on

Channel 1 to help with system rolloff (for CVBS signals)
and a flat passband response on all other channels.
Within the passband, each channel amplifies the signal
by two and adds 280mV of offset.
Typical voltage levels are shown in Figures 1 and 2.
