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 -40c to +85c. applications video amplifiers cable and satellite set-top boxes communication devices video on demand portable and handheld products personal video recorders dvd players sdtvs vcrs features dual-channel video drivers 6db output driver gain operating voltage range: 3.0v to 5.5v 15mhz wide frequency internal clamp function sag correction function rail-to-rail output ac- or dc-coupled inputs ac- or dc-coupled outputs low operating current: 5.8ma typical (dual) available in green tssop-8 and wsop-8 packages -40 to +85 operating temperature range block diagram lpf clamp 6db amp lpf clamp 6db amp in1 in2 gnd out1 out2 sag1 sag2 rev. a .4 sg micro corp www.sg-micro.com
