SGM9116
PRODUCT DESCRIPTION
The SGM9116 is a video buffer which integrates triple
6dB Gain rail-to-rail output driver and triple 3rd output
reconstruction filter, it has 35MHz -3dB bandwidth and
160V/µs slew rate. SGM9116 provides improved image
quality compared with passive LC filters and discrete
drivers solution. Operating from single supplies ranging
from +2.5V to +5.5V and sinking an ultra-low 27.5mA
quiescent current, the SGM9116 is ideally suited for
battery powered applications.
SGM9116 can be DC-coupled or AC-coupled with input
video signal, such as the output of DAC. Internal diode
clamps and bias circuitry may be used if AC-coupled
inputs are required. SGM9116 also integrates an internal
level shift circuit which avoids sync-pulse being clipped
and allows DC-coupled output. The driver in SGM9116
can drive DC or AC-coupled single (150
Ω
) or dual (75
Ω
)
loads.
The SGM9116 has lead (Pb) free SOIC-8 package and
ESD(HBM) reaches 8KV.

NOTES
1. Stresses above those listed under Absolute Maximum
Ratings may cause permanent damage to the device. This is
a stress rating only; functional operation of the device at
these or any other conditions above those indicated in the
operational section of this specification is not implied.
Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
CAUTION
This integrated circuit can be damaged by ESD if you
don’t pay attention to ESD protection. Shengbang
Micro-electronics recommends that all integrated
circuits be handled with appropriate precautions.
Failure to observe proper handling and installation
procedures can cause damage.
ESD damage can range from subtle performance
degradation to complete device failure. Precision
integrated circuits may be more susceptible to
damage because very small parametric changes could
cause the device not to meet its published
specifications.
