SGM9122

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, batteryoperated 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 -40°C to +85°C.
