SGM9119
Triple, 5th-Order, Standard
Definition Video Filter Driver
PRODUCT DESCRIPTION
The SGM9119 is a low voltage, triple video amplifier
with integrated reconstruction filters and input clamps.
Specially suited for standard definition video signals,
this device is ideal for a wide range of television and
set-top box applications.
SGM9119 offers 6dB gain rail-to-rail output driver and
5th-order output reconstruction filter on all three
channels. It has 8MHz -3dB bandwidth and 31.5V/µs
slew rate. SGM9119 provides improved image quality
compared with passive LC filters and discrete drivers
solution. Operating from single power supply ranging
from 3.3V to 5.5V and sinking a low 21mA quiescent
current, the SGM9119 is ideally suited for battery
powered applications.
SGM9119 can be DC-coupled or AC-coupled with input
video signal, such as the output stage of DAC to
eliminate out-of-band noise. The output in SGM9119
can be configured as DC- or AC-coupled output.
The SGM9119 is available in Green SOIC-8 and
MSOP-8 packages. It operates over an ambient
temperature range of -40℃ to +85℃.
