MAX9512AEE+T

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P19
General Description
The MAX9512 video filter amplifier with SmartSleep and
Y/C mixer is ideal for portable media players (PMPs),
portable DVD players, and set-top boxes (STBs). The
inputs can be directly connected to the digital-to-analog
converter (DAC) outputs. The dual reconstruction filters
remove high-frequency signals above 6.75MHz. The
Y/C-to-CVBS mixer creates a composite video signal
from luma and chroma. The four amplifiers each have
6dB of gain. The outputs can be DC-coupled to a load of
75Ω, which is equivalent to two video loads, or AC-cou-
pled to a load of 150Ω.
The SmartSleep circuitry intelligently reduces power
consumption based on the presence of the input signal
and the output loads. When the MAX9512 does not
detect the presence of sync on luma, the supply cur-
rent is reduced to less than 7µA. The device only
enables a video amplifier when there is an active video
input signal and an attached load. The video amplifier
remains on while a load is connected. If the load is dis-
connected, the video amplifier is turned off.
The MAX9512 operates from a 2.7V to 3.6V single sup-
ply and is offered in a small, 16-pin TQFN (3mm x
3mm) package. The device is specified over the -40°C
to +125°C automotive temperature range.
