SGM9110
PRODUCT DESCRIPTION
The SGM9110 is single rail-to-rail 3-pole output
reconstruction filter with a -3dB bandwidth of 8MHz
and a slew rate of 40V/µs. Operating from single
supplies ranging from +2.5V to +5.5V and sinking an
ultra-low 2.65mA quiescent current, the SGM9110 is
ideally suited for low power, battery-operated
applications.
The output swings within 100mV of GND and 170mV to
V+ with a standard back-terminated video load (150Ω).
SGM9110
employs an internal level shift circuit that
avoids sync-pulse clipping and allows DC-coupled
output. If AC-coupling is preferred, the
SGM9110
offers
a sag-correction feature that significantly reduces the
size of the output coupling capacitor.
SGM9110 has a power-down disable feature that reduces
the supply current to 2µA,
dramatically reducing power
consumption and prolonging battery life.
It is specified over the extended –40°C to +125°C
temperature range.

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.
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.
