MAX9503GEEE+

P1-P3P4-P6P7-P9P10-P12P13-P13
General Description
The MAX9503 filters and amplifies standard-definition
video signals. Maxim’s DirectDrive™ technology elimi-
nates large output-coupling capacitors and sets the
video black level to ground. The input of the MAX9503
can be directly connected to the output of a video
digital-to-analog converter (DAC). The MAX9503 pro-
vides a compact, integrated, and low-power solution.
An internal reconstruction filter smoothes the steps and
reduces the spikes on the video signal from the DAC.
The reconstruction filter typically has 3dB attenuation at
9MHz and 50dB attenuation at 27MHz, and ±1dB pass-
band flatness to 5.5MHz.
Maxim’s DirectDrive uses an integrated charge pump
and a linear regulator to create a clean negative power
supply to drive the sync below ground. The charge
pump injects so little noise into the video output that the
picture is visibly flawless.
The MAX9503 is available with +6dB (MAX9503G) and
+12dB (MAX9503M) gains. The device operates from a
2.7V to 3.6V single supply and features a 10nA low-
power shutdown mode.
The MAX9503 is offered in space-saving 16-pin QSOP
and 16-pin TQFN packages and is specified over the
-40°C to +85°C extended temperature range.
