MAX9505EEE+

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P16
General Description
The MAX9505 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. An internal reconstruction
filter smoothes the steps and reduces the spikes on the
video signal from the video digital-to-analog converter
(DAC). The input of the MAX9505 can be directly con-
nected to the output of a DAC. The MAX9505 provides
a compact, integrated, and low-power solution.
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 negative power supply
to drive the sync below ground. The charge pump injects
so little noise into the video output that the picture is visi-
bly flawless.
The MAX9505 features an internal 1.7Ω analog switch
that interfaces with a 4-pole multimedia jack. This
switch allows one of the poles to be set as a video
input, a video output, or a microphone input.
The MAX9505 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.
