Video Amp Quad 5V 14-Pin TSSOP Rail

Fabricated using the revolutionary complementary Silicon-Germanium (SiGe) BiCom3X process, the THS7374 is a low-power, single-supply 3 V to 5 V four-channel integrated video buffer. It incorporates a sixth-order Butterworth filter (able to be bypassed) which is useful as a digital-to-analog converter (DAC) reconstruction filter or an analog-to-digital converter (ADC) anti-aliasing filter. The 9.5-MHz filter is a perfect choice for SDTV video that includes composite (CVBS), s-video, Y"U"V", G"B"R" (R"G"B"), and Y"P"BP"R 480i/576i. As part of the THS7374 flexibility, the input can be configured for either ac or dc-coupled inputs. The 300-mV output level shift allows for a full sync dynamic range at the output with 0-V input. The ac-coupled modes include a transparent sync-tip clamp option for CVBS, Y", and G"B"R" signals with sync. AC-coupled biasing for C"/P"B/P"R channels can easily be achieved by adding an external resistor. The THS7374 is the perfect choice for all video buffer applications. Its rail-to-rail output stage with 6-dB gain allows for both ac and dc line driving. The ability to drive two lines per channel, or 75-O loads, allows for maximum flexibility as a video line driver. The 9.6-mA total quiescent current at 3.3 V and 0.1-µA disabled current makes it an excellent choice for portable or other power-sensitive applications. The THS7374 is available in a TSSOP-14 package that is lead-free and green (RoHS) compliant.
