3V Video Amplifier with
Internal Gain and Filter in SC70
General Description
The MAX9680 high-speed amplifier and filter is opti-
mized for portable video applications. It is specifi-
cally designed to be compatible with the video encoders
embedded in application processors with 0.4VP-P video
output. The input common-mode range includes GND,
which allows a video DAC (digital-to-analog converter)
to be DC-coupled to the MAX9680.
The output swings within 2mV of GND and 20mV to VDD
with a standard back-terminated video load (150I). An
internal level shift circuit prevents the output from satu-
rating with 0V input, thus preventing sync-pulse clipping
in common video circuits. Therefore, the MAX9680 is
ideally suited for DC-coupling to the video load.
The MAX9680 has been optimized for space-sensitive
applications by integrating internal gain setting resistors
(G = 5.2V/V) and a 2-pole video-DAC reconstruction filter.
In shutdown mode, the quiescent current is reduced to
less than 0.4FA, dramatically reducing power consump-
tion and prolonging battery life.
The MAX9680 is available in the tiny 2mm x 2.1mm,
6-pin, SC70 package.
