SGM9122
Dual Video Driver with 6dB Gain
GENERAL DESCRIPTION
The SGM9122 is a dual video 6dB amplifier. Operating
from single power supply ranging from 3.0V to 5.5V
and sinking a low 5.8mA quiescent current, the
SGM9122 is ideally suited for low power, battery-
operated applications.
Each channel has clamp function that fixes DC level of
video signal. Further more SGM9122 has SAG
correction feature that significantly reduces the size of
the output coupling capacitor.
SGM9122 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 SGM9122
can be configured as DC- or AC-coupled output.
The SGM9122 has Green TSSOP-8 and WSOP-8
packages. It operates over an ambient temperature
range of -40°C to +85°C.

NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications 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. SGMICRO 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.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the latest datasheet.
