The MAX9532 DirectDrive
specifically designed to work in harsh environments
such as automobiles. The MAX9532 provides integrat-
ed short-to-battery protection, allowing the output of the
device to survive shorts up to 18V.
Maxim’s DirectDrive technology eliminates large output
coupling 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 MAX9532 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 provides ±1dB
passband flatness of 9.5MHz and 42dB attenuation at
27MHz.
The input of the MAX9532 can be directly connected to
the output of a video DAC. The MAX9532 also features a
transparent input sync-tip clamp, allowing AC-coupling
of input signals with different DC biases.
The MAX9532 features an internal fixed gain of 4V/V. The
input full-scale video signal is nominally 0.5V
output full-scale video signal is nominally 2V
The short-to-battery protection utilizes an internal switch
in series with the amplifier output. When the MAX9532
detects that the output is short circuited to the battery
voltage, the internal switch is disabled, protecting the
MAX9532 from voltages up to 18V.
The MAX9532 is available in a 3mm x 3mm, 10-pin
