SGM9123
GENERAL DESCRIPTION
SGM9123 is a video buffer which integrates triple 6dB
Gain rail-to-rail output driver and triple 3rd output
reconstruction filter, it has 8MHz -3dB bandwidth and
44V/µs slew rate. SGM9123 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
7.4mA quiescent current, the SGM9123 is ideally
suited for battery powered applications.
SGM9123 can be DC-coupled or AC-coupled with
input video signal, such as the output stage of DAC to
eliminate out-of-band noise. Internal diode clamps
and bias circuitry may be used if AC-coupled inputs
are required. SGM9123 also integrates an internal
level shift circuit which avoids sync-pulse being
clipped and allows DC-coupled output. The drivers in
SGM9123 can drive DC or AC-coupled single (150Ω)
or dual (75
Ω)
loads.
The SGM9123 has lead (Pb) free SO-8 package and
ESD (HBM) reaches 8KV.
