6V Single-Supply Operation MAX9503 The MAX9503 filters and amplifies standard-definition video signals.
Maxim’s DirectDrive™ technology eliminates 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 provides 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 passband 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 lowpower 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.
