The SGM9131 video filter is intended to replace passive LC filters and drivers with an integrated device. Three 6th-order channels offer High Definition (HDi) filters. The SGM9131 may be directly driven by a DC-coupled DAC output or an AC-coupled signal. Internal bias circuitry provides constant bias voltage for AC-coupled inputs. The outputs can be AC- or DC-coupled. DC coupling the ;outputs removes the need for large output coupling capacitors.
The SGM9131 is available in Green SOIC-8 package. It operates over an ambient temperature range of -40℃ to +85℃.
