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.
