Maxim MAX9516 Datasheet

General Description

Operating at 1.8V from a single power supply, the
MAX9516 amplifies standard-definition video signals
and only consumes 6mW quiescent power and 12mW
average power. The MAX9516 leverages Maxim’s
DirectDrive™ technology. Combining DirectDrive with
the external positive 1.8V supply, the MAX9516 is able
to drive a 2V

P-P

video signal into a 150Ω load. The
MAX9516 has the ability to detect and report the pres­ence of a video load and reduce power consumption
when the load is not present.

The MAX9516 can detect the presence of a video load
and report a change in load through the LOAD flag.
This feature helps reduce overall system power con­sumption because the video encoder and the MAX9516
only need to be turned on when a video load is con­nected. If no load is connected, the MAX9516 is placed
in an active-detect mode and only consumes 31µW.

Maxim’s DirectDrive technology eliminates large output­coupling capacitors and sets the output video black
level near ground. DirectDrive requires an integrated
charge pump and an internal linear regulator to create
a clean negative power supply so that the amplifier can
pull the sync below ground. The charge pump injects
so little noise into the video output that the picture is
visibly flawless.

The MAX9516 features an internal reconstruction filter
that smoothes the steps and reduces the spikes on the
video signal from the video digital-to-analog converter
(DAC). The reconstruction filter typically has ±1dB
passband flatness of 7.5MHz, and 46dB (typ) attenua­tion at 27MHz.

The input of the MAX9516 can be directly connected to
the output of a video DAC. The MAX9516 also features
a transparent input sync-tip clamp, allowing AC-cou­pling of input signals with different DC biases.

The MAX9516 has an internal fixed gain of 8. The input
full-scale video signal is nominally 0.25V

P-P

, and the

output full-scale video signal is nominally 2V

P-P

.
