MAX11503EUA+T

P1-P3P4-P6P7-P8
General Description
The MAX11503 is a low-power video amplifier with a
Y/C summer and chroma mute. The device accepts an
S-video or Y/C input and sums the luma (Y) and chroma
(C) signals into a composite CVBS signal which can be
connected directly to a TV monitor. The MAX11503 drives
two terminated 75Ω video coax cables.
The MAX11503 features include chroma mute, power
save, and SAG correction. Chroma mute disables the
chroma buffer. If the device is used to combine Y and
C signals in a camera application, the chroma mute
may be used in low-light situations. This removes all
chroma including burst which causes a downstream
composite video decoder to interpret the video signal
as luminance only, thus improving image quality. SAG
correction allows small output capacitors to be used in
AC-coupled output applications.
The MAX11503 operates from a single 2.7V to 5.25V
supply, is specified over the extended -40°C to +85°C
temperature range, and is available in a small 8-pin
µMAX
®
package.
