SGM9115 is a video buffer which integrates triple 6dB Gain rail-to-rail output driver and triple 3rd output reconstruction filter, it has 9MHz -3dB bandwidth and 44V/μs slew rate. SGM9115 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 6.8mA quiescent current, the SGM9115 is ideally suited for battery powered applications. SGM9115 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. SGM9115 also integrates an internal level shift circuit which avoids sync-pulse being clipped and allows DC-coupled output. The drivers in
SGM9115 can drive DC or AC-coupled single (150Ω) or dual (75 Ω) loads.
