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.
